This enables omit-frame-pointer for i386-solaris.  I honestly haven't 
bootstrapped it, but I don't expect any problems (and if they appear, 
it's much better to fix them ;).

Committed to gcc and (shortly) to src.

How about killing mh-x86omitfp?  The x86 compiler defaults to 
-fomit-frame-pointer on most platforms now anyway.

I'd prefer that: Solaris 10+/x86 defaults to -fomit-frame-pointer for
improved debuggability (cf. gcc/config/sol2-10.h:
USE_IX86_FRAME_POINTER, USE_X86_64_FRAME_POINTER), so it would be better
leave this to the individual platforms instead.
