Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Powerpc is special here. powerpc and powerpc64 use different ABIs, so
their implementations aren't in the same files. Introduce LIBC_ARCH
and use that in preference to MACHINE_CPUARCH. Tested by amd64 and
powerpc64 builds (thanks nathanw@)

MFtbemd:

Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

Fix a typo that prevented the quad symbols from being exported
(s/SYM_MAP/SYM_MAPS/).

Reported by: kan
Approved by: re@ (Ken Smith)

Export quad symbols. They were previously commented out. These symbols
really shouldn't be exported since they should be pulled from libgcc, but
the build of some applications is broken and they expect to see them in
libc. glibc exports these symbols, although Solaris doesn't appear to,
so export them for compatibility's sake.

After discussion with: kan

Use C comments since we now preprocess these files with CPP.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Add each directory's symbol map file to SYM_MAPS.

Add symbol maps and initial symbol version definitions to libc.

- Add prototypes for __cmpdi2() and __ucmpdi2().
- Remove GCC 1 stuff.

libc_r wasn't so tied to libc for 22 months.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Remove __P() usage.

Remove 'register' keyword.

$Id$ -> $FreeBSD$

- Fix modulo bug that was masked by the correct code in libgcc.a which is
used in almost all programs unless a shared library specifically
ignores libgcc.a.

$@ -> ${.TARGET}

Change MACHINE references to MACHINE_ARCH.

Put the .PATH statement first as in all other libc Makefile.inc's.

Changed all paths to be relative to src/lib instead of src/lib/libc
so that all these makefiles can be used to build libc_r too.

Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.

Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Added prototypes.

Restored [u]cmpdi2.c which are needed for switching on [unsigned] long
long values.

Removed cmpdi2.c from ${SRCS}. I think it is no more needed than ucmpdi2.

Restored order in ${SRCS}.

limit the number of functions we pull in for 'i386'.
I still belive this stuff should go back into gcc.

Remove trailing whitespace.
