FWIW Linux does approximately the same thing. It uses it's cc-option
construct in the m32 case (presumably once upon a time non-biarch 32 bit
compilers were common) but given that we already use -m32
unconditionally in CFLAGS I guess we don't care now.

I don't actually do cross compiles myself (only because it doesn't
work... so maybe now I will) but this didn't break my native 32 bit
tools or native 64 bit Xen build so:
