Sorry, I think I confused you:
ia64-* is Intel's Itanium system. They are 64-bit only cpus (the 32-bit
emulation is too slow to be usable). It's supported by multiple
operating systems, among them HP UX, Linux, Windows. As far as I can see
it's supported directly, by 7.3.3, at least RedHat builds their ia64
version without any patches.
x86_64 is AMD's Operon/Athlon 64 system. They support concurrent 32-bit
and 64-bit. Right now only supported by Linux, BSD and Windows support
expected soon.
Thus the test must be for "x86_64-*".

Martin: you are using debian-testing, correct? I've asked a Suse
developer, and on their Linux distribution, -m64 is the default, i.e.
you don't need any switches.
