The other idea I toyed with was dynamic loading of libnuma so there's
not an install dependency for the libnuma package with the rt-tests
package. I only use five functions from libnuma, so that's not too bad
a set of function pointers to manage. Hmmm, that probably won't work
very well, since I'll still have to include numa.h. Sigh...

It's an overkill.

We are not talking about use package to be installed into millions of 
systems in binary form.

rt-tests are used by developers; developers may compile those with needed 
options.
