You could detect whether one must past `-m32' to the build system native
compiler in order to create an executable that runs on the build system, but the
answer will always be `no'.  An example of a remarkably strange configuration
that such a test would aid is a mips-unknown-linux-gnu system with a
mips64-unknown-linux-gnu toolchain installed as though native.

Why do you need this test?
