A somewhat similar situation arises on sparc64 solaris, where
executables in the 64-bit ABI can't run if the kernel is in 32-bit
mode.  The compiler can create them, but they can't run.  In gmp we
recommended what Guido said, fake up a --build to make it look like a
cross compile.  --build=none for instance, since gmp (and I would
guess a lot of packages) doesn't pay attention to the actual build
system type.
