PATCH: Update (*_FREEBSD_*) config/rs6000/sysv4.h to match initial system compiler

[Loren James Rittle]

Attn: David Edelsohn or Geoff Keating

Under private cover, David O'Brien sent me a few patches developed
while he ported/stabilized gcc 3.2.X/3.3 to new CPUs members of the
FreeBSD family.  I believe that the second and third hunks I could
perhaps technically self-approve now.  But since this patch covers
stuff outside a freebsd-specific configuration file, I'd like an
RS6000 maintainer to OK it as well for mainline and 3.3.  I will only
defend the first thunk weakly since my analysis is that some ports
(e.g. netbsd) have started to define only the __X__ style
configuration macros.  The other two thunks are merely updating to
match a refinement that hit all other FreeBSD/CPU ports.

Thanks,
Loren

	* config/rs6000/sysv4.h (_LITTLE_ENDIAN): Use __LITTLE_ENDIAN__ instead.
	(CPP_OS_FREEBSD_SPEC): Add __ELF__ to mirror other FreeBSD ports.
	(LINK_OS_FREEBSD_SPEC): Mirror conventions on other FreeBSD ports.
