A patch such as this would be very helpful for me, as I just want to
use ghci/etc. on x86-64 and don't really care much about e.g. the very
highest-quality codegen. I hacked around this in various ways to get
the stock binary i386 distribution to run on x86-64, but would prefer
to use something less hackish than shell script wrappers for gcc(1) and
as(1) that pass the 32-bit forcing arguments...

Also, the Debian ghc package on sparc64 (32-bit) seems to need some kind
of update; ghc proper is fine, but ghci cores. Maybe I should file a bug.
Alpha looks clean, though. I've not tried on ia64, ppc64, or mips64 yet.
Running on my sparc64 box would be nice b/c it has more cpus, RAM, and
registers. =)
