184595ed9f META_MODE: Fix build-tools still sometimes rebuilding during target build.
In a cross-build, the build-tools are native host binaries.  We do not
want to rebuild them when building for the target.  Bmake previously
did not support checking .NOMETA on an existing target, so .NOMETA_CMP
was used here.  However, .NOMETA_CMP still triggers meta mode conditions
if the number of commands or the command changes.  In r312467 the paths
to build ncurses files were modified and thus triggered meta mode to
rebuild the build tools (make_keys, make_hash) in ncurses during the
target build.  Bmake 20160604 committed in r301462 changed .NOMETA to
also skip meta mode logic for an existing .meta file as well, thus it
is now the proper fix here.

I explored moving the build-tools output to WORLDTMP/tools with
relatively good success, but have concerns that doing so would be
problematic for downstream vendors who use LOCAL_TOOL_DIRS and
expect the tools to be in current OBJDIR for the target.  It also
adds more complexity into finding the tools during target build
and handling of where they are for rescue/rescue and
mkcsmapper_static/mkesdb_static which should really not be connected in
build-tools anyway.

9f7f2f2cc0 Set -m32 in MD LIB32CPUCFLAGS rather than MI LIB32CFLAGS.
Both amd64 and powerpc64 use -m32 to compile 32-bit binaries, but not
all platforms follow this convention.  Move the -m32 compile flag into
the per-architecture flags to accomodate other architectures.

5e58860345 Fix in-tree GCC builds after r304681.
There were a few issues.
- In-tree GCC won't have X_COMPILER_TYPE defined but will have
  WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can
  be used.  Make the clang check specific to clang as well to ensure
  -target doesn't leak into a GCC build.
- When using a cross-compiler GCC (with a default sysroot or arch) and also
  passing --sysroot, it basically forgets all internal paths for
  libraries.  We've already worked around this quite a bit for
  the external toolchains.  Now for the in-tree bootstrap cross-compiler
  GCC, also pass in the needed -B${WORLDTMP}/usr/lib to find the crt
  object files, but also -isystem and -L to fix the paths.  This creates
  quite a spammy build log, but it is clear and still achieves the goals
  and stays consistent between internal and external build flags.
  Reducing the spam by using the '=' prefix feature will help and be
  done later.

dacbc02e78 Don't disable binutils/elftoolchain bootstrapping with external compiler.
This was a regression from r300349.

Setting MK_CROSS_COMPILER=no forces the compiler bootstraping *and* the
binutils/elftoolchain bootstrapping to be disabled in share/mk/src.opts.mk.
The only intent with using an external compiler is to disable bootstrapping of
the compiler.  The binutils/elftoolchain bootstrapping must still occur unless
XAS is set.  This did not affect WITH_SYSTEM_COMPILER.

Now that setting an external compiler sets both MK_CLANG_BOOTSTRAP and
MK_GCC_BOOTSTRAP to no, and MK_CROSS_COMPILER does the same via
share/mk/src/opts.mk, remove redundant logic that checks for
MK_CROSS_COMPILER.  It will not always be true now that MK_CROSS_COMPILER==no
when an external compiler is used and --sysroot/-target is needed.

1e1f5317b7 WITH_SYSTEM_COMPILER: Avoid using GCC4.8+ logic on native GCC4.2 platforms.
As the XXX notes, these should really be checking MK_GNUCXX since there is
already a version check in share/mk/src.opts.mk to disable it.  Fixing that
here is more complex though.  This could also be using X_COMPILER_FEATURES
but uses X_COMPILER_VERSION to keep in sync with the src.opts.mk logic.

42d9d45fb8 Fix native powerpc64 build of lib32 with in-tree GCC.
- This was broken by r300350 and r300885.
- Add some comments around the external GCC logic since it is spread out
  and in need of some cleanup.
- The problem was that X_COMPILER_TYPE is always defined from CC->XCC's
  default, so if /usr/bin/cc is GCC (as it is on native powerpc64) then
  X_COMPILER_TYPE was getting GCC and triggering the external logic in
  Makefile.libcompat.  It was intended to always provide -isystem with
  GCC since --sysroot is used into the lib32 sysroot which won't modify
  the header path without the -isystem.  The use of the libc++/std=c++11
  override was only intended to be used for external compilers though
  (more accurately GCC 4.8+ but that's a separate assumption to
  cleanup).  Apply the same logic from Makefile.inc1 to Makefile.libcompat
  to only add the libc++ override when needed for external compilers.

c2a2f8cf8b Use -L to specify compat32 library paths instead of -Y
-Y is an uncommon linker option that is rather similar to -L.  In
discussion with Peter it seems early amd64 development might have
required the -Y-specific behaviour, but it is no longer necessary.

Switch to -L which is more widely supported and much more commonly
used, to make it easier to link the FreeBSD base system with linkers
other than ld.bfd.

dd479c1b47 Libcompat: Set build tools in environment rather than make overrides.
This allows the CXX hack in r300917 for external GCC to work for
the lib32 build.  It is also the same pattern as the native
build uses by adding the tools into CROSSENV for external
toolchain, rather than make overrides.

288155afbb Move external GCC compiler hacks to bsd.sys.mk.
This allows respecting -nostdinc, -nostdinc++ and -nostdlib before
making the decision to add in -isystem, etc.  The -isystem flags
are problematic for building lib/libc++ and lib/libcxxrt which wants
to only use its own headers.

More information the need of these flags can be found at
https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html

This also reverts r300873.

64d40c9f8c Build libcompat (lib32) with a --sysroot pointing into its stage directory.
This overrides the cross-compiler's default sysroot to use the WORLD32's
sysroot for building the lib32 libraries.  Previously the cross-compiler
would default the sysroot to the 64bit WORLDTMP and -B/-L/-isystem flags
were used to build using the lib32 files.  This leads to multiple issues
discussed later.  Some extra headers are now needed to be staged since the
64bit WORLDTMP is not referenced at all for headers.  The 64bit WORLDTMP
is still used via PATH for build tools.  Overriding the default
target/arch is retained in the CC/CXX overrides.

This allows reverting the LDSCRIPT rewriting in installworld from r296921 and
r235122, thus allowing read-only objdirs to work for installing again.

This removes the need for _LDSCRIPTROOT.

This allows progressing the change to always use --sysroot for the build
rather than only relying on the cross-compiler's default sysroot.  The
work for that is in D3970 and needed to resolve WITHOUT_CROSS_COMPILER
not using a --sysroot [1].

54f229f3df LIBRARIES_ONLY should only be defined during install32.
r245561 added it to prevent extra files from being installed during
the install32 phase (to prevent duplicates in the meta log with -DNO_ROOT).
The flag should not be passed during build32 though since it may
prevent staging of includes during the 'make includes' phase on
library directories.

4e2d26ce1b Use the newly minted Makefile.libcompat to implement libsoft libraries
for the armv6 ABI switch. This also make WITH_LIBSOFT functional on
the arm platform. As a transition thing, this seems to work even
without switching the ABI (we basically build the same libraries
twice when MK_LIBSOFT=yes until the ABI cut over next
month). MK_LIBSOFT remains default no.

e362e0e49e Move Makefile.lib32 to Makefile.libcompat and generalize it.
This is in preparation for LIBSOFT.

This file only supports *1* LIBCOMPAT value currently and must be capitalized.
In Makefile.libcompat given LIBCOMPAT=FOO there can be values set for
LIBFOOCFLAGS, LIBFOOCPUFLAGS, LIBFOOWMAKEENV, LIBFOOWMAKEFLAGS, LIBFOOCPUFLAGS,
and LIBFOODTRACE.  These will have the standard cross-build values appended
onto them.

This could be extended to support multiple libcompat libraries in the future
once there is a need.
