Hi Geoff,

This does fundamentally change the affect that ARCH has on the
build - that is, it now has an affect. And this worries me in
the context of cross-compiling. However, after reasonably extensive
testing of all the supported architectures, I have convinced myself
that it at least for cross-compiling its ok :-)

I have gone ahead and applied this change. But if people
could test building various architectures, I would appreciate it.
