52dbe95f4d Include bsd.compat.mk early from sys.mk, enough for makefiles
using conditional statements to see the new spellings of NO_*

96b8536954 Compiling with 'strict-aliasing' optimization breaks some [notable] ports.
GCC turns on 'strict-aliasing' optimization at all levels above -O[1], so
explicitly turn it off when using compiling with the -O2 optimization level.

acabf29a1b Use the '+' flag to make make recurse into sub-directories even when
given -n. For POLA reasons this behaviour is switched on only when
at least two -n flags are given to make. One -n flag keeps the old behaviour
of showing the shell command that would recurse into the sub-directories.

88d2251a91 Removed conditional include of /etc/make.conf.local and the error for the
existence of this file.  This stopped working more than 4 years ago when
the generation of the error was added in rev.1.44.  The .error directive
gives fatal errors, so stale /etc/make.conf.local files must have been
gone away more than 4 years on systems where make(1) works.

d17387acd4 Fixed breakage of POSIX support in rev.1.31. -pipe was added to
CFLAGS in all cases, but POSIX requires a default of -O.  Adding
-pipe unconditionally still is still broken for non-gcc compilers

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

2bdaf7e81c Don't include bsd.own.mk from sys.mk, this makes it impossible
to use ``.if defined()'' inside bsd.own.mk to test for defines
in individual makefiles.  For example, setting DEBUG_FLAGS in
Makefile didn't take the desired effect on the STRIP assignment.

Added bsd.init.mk (like in NetBSD) that handles the inclusion
of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that
"build something".

Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back
to sys.mk (several source tree makefiles want to check it early)
and removed MACHINE_ARCH initialization (it's hard to see from
looking at the commitlogs what the problem was at the time, but
now it serves no purpose).

Prohibit the direct inclusion of bsd.man.mk and bsd.libnames.mk.

Protect bsd.obj.mk from repetitive inclusion.  Prohibiting the
direct inclusion of bsd.obj.mk might be a good idea too.

(See commit log for usr.bin/xlint/Makefile,v 1.11 for what was wrong
with enabling build of lint libraries in rev. 1.12.)

This fixes cross-arch compiles (running binaries for a different arch
when generating lint.7 and lint libraries) and cross-branch compiles
(4.x -> 5.0 buildworld should be working again).

0af93efb4d __MAKE_CONF?=/etc/make.conf
Use this where we are now using /etc/make.conf.

This allows people to override the current default of always including
/etc/make.conf.  Setting __MAKE_CONF to /dev/null disables it
completely, while setting it to something else allows one to override
what is on the system.  This can be desirable in situations where a
machine has many users and some of them want different defaults, or
defaults appropriate to cross building to be different than those for
normal building.

d33a962d07 Move /etc/defaults/make.conf to /usr/share/examples/etc/make.conf as
discussed on the arch@ mailinglist (after repo-copy).

sys.mk will .error if it finds /etc/defaults/make.conf but include
it anyways (this is the same behaviour as with the make.conf.local
removal).

/usr/share/examples/etc/make.conf has BDEFLAGS commented out now,
since it's only an example file.

Adjust all textes that talk about make.conf or defaults/make.conf to
match the new situation.

62d90fb793 Overhaul the MACHINE_CPU behaviour:
* Rip out MACHINE_CPU stuff from sys.mk and include a new <bsd.cpu.mk>
  after we pull in /etc/make.conf.  We need to do it afterwards so we can
  react to the user setting of the:

* CPUTYPE variable, which contains the CPU type which the user wants to
  optimize for.  For example, if you want your binaries to only run on an
  i686-class machine (or higher), set this to i686.  If you want to support
  running binaries on a variety of CPU generations, set this to the lowest
  common denominator.  Supported values are listed in make.conf.

* bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the
  (hopefully) correct unordered list of CPU types which should be used on
  that CPU.  For example, an AMD k6 CPU wants any of the following:
    k6 k5 i586 i486 i386
  This is still an unordered list so the client makefile logic is simple -
  client makefiles need to test for the various elements of the set in
  decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before.
  The various MACHINE_CPU lists are believed to be correct, but should be
  checked.

* If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization
  settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc).  Release
  builders and developers of third-party software need to make sure not to
  enable CPU-specific optimization when generating code intended to be
  portable.  We probably need to move to an /etc/world.conf to allow the
  optimization stuff to be applied separately to world/kernel and external
  compilations, but it's not any worse a problem than it was before.

* Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE.

* Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc
  (only i386, alpha and ia64 first, since those are the minimally-working
  ports.  Other architecture porters, please feel free to add the relevant
  gunk for your platform).

9cd5532f9c Turns out we do need to do bootstrapping of MACHINE_CPU here: make(1) won't
set the variable until you rebuild it, and the alternative is to be stuck
playing games with ``.if defined(MACHINE_CPU) && ... '' for all eternity.
We now set up the reasonable default for i386 and alpha here -- given this
it probably makes sense to remove the corresponding code from make(1).

0937df81ca Introduce support for using OpenSSL ASM optimizations. This is done
through the use of a new build directive, MACHINE_CPU, which contains a
list of the CPU generations/features for which optimizations are desired.
This feature will be extended to cover the ports tree in the future.

Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.

Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture).  Currently this is i386 for the i386 architecture and ev4
for the alpha.  sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.

Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems.  For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.
