selftests: vm: enable cross-compilation

Browse source

Selftests vm builds break when doing cross-compilation.  The Makefile
MACHINE variable incorrectly picks upp the host machine architecture.

If the CROSS_COMPILE variable is set, dig out the target host architecture
from CROSS_COMPILE, instead of calling uname.
