selftests: kvm: fix for compilers that do not support -no-pie
-no-pie was added to GCC at the same time as their configuration option --enable-default-pie. Compilers that were built before do not have -no-pie, but they also do not need it. Detect the option at build time. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
