    Fixes "internal compiler error: in do_SUBST" on compiling
    floating point ops with -msoft-float or -m68010 on LP64 hosts,
    and may also close PR toolchain/38359.  Tested on alpha.


oh really.  nice find.

i wonder if this means most of sun2 can be built with
-O again?  i had disabled it but my build platform is
amd64 so i was seeing errors _all over the place_ so i
disabled it more globally.
