Not needed on modern systems without external FPU

TBD on i386 it is only needed for true 386s. Could remove it there
TBD for >= 486

Since we are merging x86 and x86-64, I think it would be nice at least to CC Thomas on patches that increase 32/64-bit differences... because won't this patch have to be partial un-done when we merge i386 and x86-64?
