rt-tests: NUMA optional for make rpm

I'm not sure if this is worth fixing, but...

rt-tests can be built without NUMA:

make NUMA=0

But "make rpm" does not have a way to be successful without NUMA:

build_rt-tests_0.85> make rpm
for F in cyclictest signaltest pi_stress rt-migrate-test ptsematest sigwaittest svsematest pmqtest sendme pip_stress hackbench *.o .depend *.*~ *.orig *.rej rt-tests.spec *.d *.a ChangeLog; do find -type f -name $F | xargs rm -f; done rm -f hwlatdetect
rm -f tags

mkdir -p tmp/rt-tests
cp -r Makefile COPYING ChangeLog src tmp/rt-tests
tar -C tmp -czf rt-tests-0.85.tar.gz rt-tests
rm -f ChangeLog
cp rt-tests-0.85.tar.gz releases
sed s/__VERSION__/0.85/ <rt-tests.spec-in >rt-tests.spec

error: Failed build dependencies:

           numactl-devel is needed by rt-tests-0.85-1.fc12.src

make: *** [rpm] Error 1

The following patch allows the rpm to be built without NUMA, with the command:

make NUMA=0 rpm

This is a somewhat ugly implementation, other suggestions are welcome.
