Users can now build kvm-unit-tests as efi apps by supplying an extra
argument when invoking configure:

$> ./configure --enable-efi

This patch is based on an earlier version by
Andrew Jones <drjones@redhat.com>

nit: not really needed as x86 doesn't allow other page sizes, arm64
already forces 4096 above, and arm32 doesn't support efi.
