[PATCH][roland/nptl] Link tst-timer against librt only when subdir is rt

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Hi Roland,

I've started the build for roland/nptl in rawhide.  Among the changes
I had to make for rtkaio, there's a change that is probably relevant
upstream, which is to link tst-timer against librt only when the
subdir is rt.  This check was in place earlier, but was removed during
the move.  OK to put it back?

	when the subdir is rt.
