powerpc: Fix FPU post related link warnings

Thanks for pointing out. I have to admit that I had completely forgotten about these.

Hm, unfortunately this appears to have stopped working.

The two objects that are flagged as "Tag_GNU_Power_ABI_FP: Hard float" are post/lib_powerpc/fpu/acc1.o and post/lib_powerpc/fpu/20010226-1.o

Both corresponding source files have the GNU_FPOST_ATTR macro...

It appears with GCC 4.6.1 the explicit "-mhard-float" command line option takes precedence over the ``asm(".gnu_attribute 4, 2");'' in the source file :-(

Is there any way to manually edit the attribute in the object file, using ld or elfedit or ... ?

Best regards,

Wolfgang Denk
