The issue is there are references to sfp-exceptions.o functions in the PowerPC
FreeBSD case, and sfp-exceptions.o is not built.  I tend to think using:

        #ifdef __FLOAT128__

is cleaner at this point of time (stage4) than trying to make sure all of the
different PowerPC systems build correctly by adding sfp-exceptions.c to the
build list.
