Ah, OK, thanks.

When I see a configure that uses gcc by default, then I defer
everything to the compiler driver since its the one that will be
selecting the programs to run.

Hmmm.. OK. Should I bring this up with the Debian folks? They provide
the platform; and if its not quite correct, then they should be the
ones who correct it.

Also, on Debian:

    # gcc -dumpmachine 2>&1 | grep x32
    x86_64-linux-gnux32

So it appears to be detectable in a default configuration without the
need to do anything special (at least on Debian).

(Usually OS X experiences these types of pain points, not GNU Linux).

Thanks again.
