Subject: [PATCH 2/3] At least try building for other archs than x86*

Allow attempting to build for other architectures than x86 and x86_64,
whether or not the build will succeed or produce sane output is another
question... It emits plenty of warnings about it now though...

Configuration of the FPU controller is disabled on all but x86*, and the
uninformed hope and prayer is that defaults will be fine without messing
with them.
