Hi Richard,

Thank you for a review.

I've removed the changes to linux64.h.  As you point out, one definition 
is enough.

Actually we don't need the duplicate make rules, so I've removed t-crtfm 
for the next iteration.

However, we still need to add crtfastmath.o to EXTRA_PARTS in t-crtfm or 
to extra_parts in config.gcc because libgcc/Makefile.in checks to see if 
EXTRA_PARTS from libgcc and EXTRA_PARTS from gcc match.

Anyway, I'll post the next iteration shortly.

Thanks,
