implemented all along: by passing AS, CC, CXX and LD on the commandline
of the sub-make instead of in the environment of the sub-make.

1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to
halting when sub-commands fail. Add "set -e" to compound commands so
that bmake is informed when sub-commands fail.
6. Make sure crunchgen uses the same make as the rest of the build. This
is important when the make utility isn't called make (but bmake for
example).
7. While here, add support for using MAKEOBJDIR to set the object tree
location. It's the second alternative bmake looks for when determining
the actual object directory (= .OBJDIR).

type of compiler is being used (currently clang or gcc). COMPILER_TYPE
is set in the new bsd.compiler.mk file based on the value of the CC
variable or, should it prove informative, by running ${CC} --version
and examining the output.
To avoid negative performance impacts in the default case and correct
value for COMPILER_TYPE type is determined and passed in the environment
of submake instances while building world.
Replace adhoc attempts at determining the compiler type by examining
CC or MK_CLANG_IS_CC with checks of COMPILER_TYPE. This eliminates
bootstrapping complications when first setting WITH_CLANG_IS_CC.

Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb
This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.
This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

stages (build-tools, cross-tools, etc) of the build, so we can detect in
bsd.*.mk whether to pass compiler-specific flags to ${CC}.
In particular, this commit will allow using WITH_CLANG_IS_CC when the
base compiler is still gcc, and when ${CC}, ${CXX} and ${CPP} are left
at their defaults. The early stages will then be built using gcc, and
no clang-specific flags will be passed to it. The later stages will be
built as usual.
The EARLY_BUILD define can also serve other uses, such as building the
world stage C++ executables with libc++ instead of libstdc++: during the
early build stages, we cannot assume libc++ is already available, so we
must still build with libstdc++ at that time.

several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.
the cross-tools stage, if CC=clang and WITH_CLANG_IS_CC is not set.
This causes no 'cc' to be installed in the temporary cross-tools tree,
making lint fall over later in the build, because it ignores ${CC} and
attempts to run 'cc' anyway.
To fix this, only skip building gcc during cross-tools, if WITHOUT_GCC
is set, or if WITH_CLANG_IS_CC is set.

This shaves off some build time, because the required libraries are now

three times.
Also, if you build world using WITHOUT_CLANG= in src.conf(5), no llvm or

make.conf(5), while allowing the build32 stage on 64-bit architectures
to still override them, so that stage can successfully build 32-bit
compatibility libraries.
Explanation:
1) The build32 stage sets environment variables CC, CXX, AS and LD for
its sub-make, to add 32-bit specific flags (-m32 and such).
2) The sub-make reads sys.mk, encounters CC?= and CXX?= assignments, so
does not alter them.
3) After some other stuff, sys.mk reads /etc/make.conf. When you have
"CC=xxx" and "CXX=yyy" statements in there, they will *override* the
build32-supplied CC/CXX values, nullifying the 32-bit specific flags.
4) Thus all objects get built as 64-bit anyway, and since LD is usually
not set in make.conf, it still has the 32-bit flags!
5) Now, whenever something is linked, you will get a "ld: Relocatable
linking with relocations from format elf64-x86-64-freebsd (foo.o) to
format elf32-i386-freebsd (bar.o) is not supported" error.
Fix this by adding "-ECC -ECXX -EAS -ELD" to the build32 sub-make
invocation, which forces those environment variables to always override
any assignment in makefiles. Thus making it possible to simply set:
CC=my-cc
CXX=my-c++
in your make.conf, or specify a path, even:
CC=/usr/local/bin/other-cc
CXX=/usr/local/bin/other-c++
Note this was never a problem on i386, since it has no build32 stage.
