Hello!

Some soft-fp symbols are present only on 32bit i386 targets and some
only on 64bit.  Attached patch adds versions only to existing symbols.
 See also [1].

	* config/i386/t-sol2 (__copysigntf3, __fabstf3): Disable for
	64bit targets.
	(__fixtfti, __fixunstfti, __floattitf, __floatuntitf): Enable only
	for 64bit targets.

OK for mainline?

Committed as obvious, after Rainer succesfully tested the patch on x86 solaris:

"A i386-pc-solaris2.10 bootstrap completed without regressions and the
versioning information in the 32 and 64-bit libgcc_s.so.1 is unchanged
(verified with pvs -dsvo)."
