Right.  Crosstool does not generate biarch compilers.
If you use crosstool to build a compiler that targets x86_64,
that compiler only targets x86_64, not i386...i686.

Sorry; I simply haven't added that yet.
But this isn't usually a problem, since you can just generate
two compilers, and choose between them instead of passing -m32.
