FYI: HEAD: avoid bogus output of runpath test

[Ralf Wildenhues]

I've applied this rather obvious patch to HEAD.

There is still a problem related to shlibpath_overrides_runpath on
GNU/Linux on ppc64 with a GNU ld that sets DT_RUNPATH which I haven't 
analyzed yet; it is failing some tests, because uninstalled libs are not
found correctly.

Cheers,
Ralf
