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

c19a8e0670 The transition time for -Werror has been gone for a while. We are now
sufficiently clean that we can fix any new problems or mark individual
files as not being ready for -Werror.

3c9d896571 Quick fix for high resolution kernel profiling on i386's. Use
-finstrument-functions instead of -mprofiler-epilogue.  The former
works essentially the same as the latter but has a higher overhead
(about 22 more bytes per function for passing unused args to the
profiling functions).

Removed all traces of the IDENT Makefile variable, which had been
reduced to just a place for holding profiling's contribution to CFLAGS
(the IDENT that gives the kernel identity was renamed to KERN_IDENT).

8365569883 Moved the setting of all profiling-related variables except the key one
(PROFLEVEL) to kern.pre.mk so that it is easier to manage.  Bumped config
version to match.

Moved the check for cputype being configured to a less bogus place in
mkmakefile.c.

25a157bc6c Remove the setting of 'FMT'. We now do ELF by default, so only bother
to increase the lenght of the command line if needed.  The setting of FMT
also gets in the cross bootstrapping way for new platforms.

2faccca61a Turn on -Werror by default. This is is easily turned off, by either:
- fix the warnings, they are there for a reason!
- add -DNO_ERROR to your make(1) command.
- add 'makeoptions NO_WERROR=true' to your kernel config.
- add 'nowerror' to conf/files* that have warnings that should be fixed
  due to tracking 3rd party vendor code.
- add 'nowerror' to conf/files* where the warning is false due to a
  compiler bug and fixing it with brute force would be too expensive.

There are some very sloppy warnings in our kernel build, come on folks!

'make release' uses -DNO_WERROR intentionally.

7a2eb19dbf Commit some infrastructure for turning on -Werror for kernel compiles.
It doesn't actually do it yet though.  This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on.  make -DNO_WERROR would also bypass all of it.

0b3178a45c Eliminate the use of commons in the kernel and modules,
simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.

Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.

Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules).  Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.

Provide a mechanism for controlling the export of symbols from
the module namespace.  The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported.  Non-exported symbols are converted to
local symbols.  If EXPORT_SYMS is not set, all global symbols are
currently exported.  This behaviour is expected to change (to
exporting no symbols) once modules have been converted.

from kern.post.mk so port makefiles can augment it.

26a42e7c88 Compile all kernels with "-ffreestanding":
Assert that compilation takes place in a freestanding environment. This
	implies `-fno-builtin'. A freestanding environment is one in which the
	standard library may not exist, and program startup may not necessarily be
	at main. The most obvious example is an OS kernel. This is equivalent to
	`-fno-hosted'.

4e8764288f Move all: target to kern.pre.mk so it matters less where you include
kern.post.mk.

# this should allow us to move kern.post.mk to the last line of the makefiles,
# but I'll do that slowly as I verify that one can do that w/o breaking things.

41c8eb3039 Factor the common parts of the Makefile.foo files. This introduces two
new files: kern.pre.mk, which contains most of the definitions, and
kern.post.mk, which contains most of the rules.

I've tested this on i386 and pc98.  I have had feedback on the sparc64
port, but no reports from anybody on alpha, ia64 or powerpc.  I
appologize in advance if I've broken you.
