OK, I will just remove the %config marking.

It's not that easy for the .so plugins to be out of the standard library path.
libibverbs uses dlopen() without a full path to open the plugin.  This means
that the standard library path is used to find the .so.  This has the advantage
that we don't have to reinvent all the library path configuration stuff; for
example the user can use LD_LIBRARY_PATH to point to a different version of a
plugin if desired, or optimized builds can be put in /lib/tls/i686/sse2, etc.

I guess the main point is that the upstream libibverbs will only search the
standard library path, and the Fedora package keeps this behavior.  So there's
not really any way to change this without redoing the Fedora libibverbs and
libmthca package, diverging from upstream, and causing pain for users who want
to install unmodified upstream plugins (there are several others not yet
packaged for Fedora, eg libcxgb3, libipathverbs, libehca).
