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

Teach our toolchain how to generate 64-bit PowerPC binaries. This fixes

2010-07-10T02:29:22Z

a variety of bugs in binutils related to handling of 64-bit PPC ELF, provides a GCC configuration for 64-bit PowerPC on FreeBSD, and associated build systems tweaks. Obtained from: projects/ppc64

Often reported issue with newer ld is:

2010-06-18T11:09:51Z

error in /usr/lib/crtendS.o(.eh_frame); no .eh_frame_hdr table will be created. The issue is that crtend is compiled with unwind table, and also it places the special CIE into the .eh_frame indicating the end of section, that is located before generated unwind table. New ld has assertion that verifies that closing CIE is indeed the last CIE, causing the crypting message to be issued, and refusing to generate dwarf unwind. Add -fno-asynchronous-unwind-tables to disable unwind table generation for crtbegin/crtend. While there, disable omitting the frame pointer [1].

Revert previous commit. The prototype has been moved to unistd.h

Add -D_OSRELDATE_H to CFLAGS to prevent the declaration of

2008-09-26T15:00:18Z

getosreldate() in assembler source files. We still get the definition of __FreeBSD_version this way, because it's outside the standard multiple-inclusion protection trick. All this is specific to ia64.

Enable GCC stack protection (aka Propolice) for userland:

- It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

Remove one more alpha leftover.

Back out last commit -- it breaks sparc64 build which has

2007-10-13T05:50:43Z

more than one .c file in SRCS.

Minor tweak to finding BEG/END source.
