I enabled it for sparc now. Although llvm-gcc now supports 128 bit
long double, sparc back end does not support long doubles yet (it
does not have quad fp registers or instructions yet). Hence xgcc fails
to compile __powitf2.o which belongs to libgcc.
I added a FIXME comment.

When I commented out tm.h, gmon-sol2.c compiles fine. Can I just
commented out tm.h from gmon-sol2.c?
