description:
ARM EABI (AAPCS) uses different names for the softfloat routines that
the normal GCC ones.  So after we redefine softfloat's to be what (old) GCC
wants, we redefined the old GCC names to what ARM EABI want (but only if we
are using ARM EABI).  We do this for routines not compiled by softfloat so
can just have these redefinitions in one place.
