Log message:
	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
	on Solaris to use Sun assembler would do.
	Including adding the -Qy flag, which isn't important.
	At least for x86, Sparc is still building to see, and Sparc64
	hasn't been tried far enough.
	
	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?
	
	Notice that Sun assembler has -K PIC flag, but passing it
	for x86/amd64 gcc output errors, and gcc doesn't pass it.
	
	Notice that though documentation says you can use two part
	GNU configurations like sparc-solaris2.10, I seem to get
	burned repeatedly doing that. Here I change to sparc-sun-solaris2.10
	and that might have been necessary.
	There are supposed to be two sets of names, the user supplied
	possibly shorter one, and the "more canonical" one.
	
	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,
	now that I no longer hunt around for GNU as, but just always use
	Sun /usr/bin/ccs/as.
	
	Port this change from gcc 4.4.0:

	* config/i386/sol2-10.h [!HAVE_AS_IX86_DIFF_SECT_DELTA]
	(ASM_OUTPUT_DWARF_PCREL): Define.
	
	Which fixes AMD64_SOLARIS -fPIC -funwind-tables with Sun assembler.
