[ARM] libgcc: include crtfastmath.o

[Christophe Lyon]

Hi,

On arm*-*-eabi*, arm*-*-symbianelf*, arm*-*-rtems* targets,
crtfastmath.o is not part of $extra_parts, which means that it is not
built, even though the make build rule is present via the inclusion of
t-crtfm.

The impact is that the link fails when using -ffast-math.

The attached patch adds crtfastmath.o to $extra_parts, for
arm*-*-eabi*, arm*-*-symbianelf*, arm*-*-rtems* targets.

I tested on arm-none-eabi, and I am not sure if this is correct for
symbian/rtems.

OK? Or should I restrict the change to arm*-*-eabi* ?

Thanks,

Christophe.
