[M3commit] CVS Update: cm3

[Jay K]

diff attached
really it's not that interesting -- all just Solaris configurys/m3makefile/python/script stuff and trivially porting a small change from gcc 4.4.0, just a few lines added in x86/solaris specific file.

> Use Sun assembler on I386_SOLARIS, AMD64_SOLARIS.

> Tweak various Solaris code around C and assembly flags.
> With an eye toward matching what gcc configured

> Including adding the -Qy flag, which isn't important.
> At least for x86, Sparc is still building to see, and Sparc64

> Switch to "small model PIC" by default.
> -xcode=pic13 vs. -xcode=pic32
> Seems no ideal solution here.

> Downgrade a bit more from i586 to i686.
> I do wonder though, maybe we should only do i586 where
> users ask -- not all x86 platforms.
> Maybe a "phone home" feature that collects uname -a or such?

> and that might have been necessary.
> There are supposed to be two sets of names, the user supplied

> Add -xF switch to Sun cc.
> It sounds like this might enable linker dead stripping.
> I should test out the difference.

> Remove the distinction in pylib.py between CC in make.sh vs. Makefile,
