The one thing I like about this is that it gives you confirmation of
what happens when you fool with PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR.
It would give you confirmation of how pkg-config will actually behave.

It's not a big deal, though. This is obviously not essential to the
operation of pkg-config.
