We've been back and forth around this many times, see most recently
revision 1.48 of asm-source.exp.  Let's not go around it again.  I
think there was some problem with using those options.

But it's supposed to skip the entire test if there's any multilib
flags; so if you're generating binaries you can't run, I wonder if
you've got the defaults messed up somehow?
