Avoid (some) ppc cross-compilation problems

[..snip..]

A recent kvm merge with qemu brought code for 64bit power that broke cross
compilation. The issue is caused by configure trying to execute target
architecture binaries where configure is executed.

[..snip..]

The patch is based on Hollis's Blanchard idea.
