macros on amd64 and i386. Move the definition to machine/param.h.
kgdb defines INKERNEL() too, the conflict is resolved by renaming kgdb
version to PINKERNEL().
On i386, correct the lowest kernel address. After the shared page was
introduced, USRSTACK no longer points to the last user address + 1 [*]

Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.
This makes /lib being populated again.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

Clang's OpenMP support will emit Intel OpenMP API library calls,
and will therefore require libiomp (or whatever name is settled on).
An up-to-date version of libgomp is included in ports or pkg GCC.
Thus, there is no reason to build base libgomp without base system GCC.

Initial support for FreeBSD specific routines related to counting

Fix "detection" of the <sys/sysctl> header which upstream seems to have
done wrong.

This is not likely to make it into a release and is basically disabled

ELF toolchain readelf lacked some functionality at the time other tools
(like size, strip, nm, etc.) were switched over to the ELF toolchain
versions. That has been addressed as of the last update, so we can add

Some users build FreeBSD as non-root in Perforce workspaces. By default,
Perforce sets files read-only unless they're explicitly being edited.
As a result, the -f argument must be used to cp in order to override the
read-only flag when copying source files to object directories. Bare use of
'cp' should be avoided in the future.
Update all current users of 'cp' in the src tree.

Prior to this change the build could fail as follows, if gperf is not
available (or fails):
- make(1) stops due to the gperf error, but an empty target file
(cfns.h) is still created
- the empty cfns.h is newer than the source cfns.gperf so it is not
regenerated on subsequent builds
- the gcc build fails (undefined reference to libc_name_p)

LLVM/Clang generates relocations that our binutils doesn't understand, but newer
binutils does. I got permission from the author of a series of patches to
relicense them as GPLv2 for use in FreeBSD. The upstream git hashes are:

With the import of clang 3.5, and a few backported patches, we should be able to
move powerpc and powerpc64 to clang-as-cc soon.
Test Plan: Passes make tinderbox, so no regressions. Binaries built with clang
run on powerpc64.
