Install pkgconfig into libdir instead of datadir

The installed libraries will be installed into libdir because they are
architecture specific. Consequently, the pkgconfig files can not be
architecture independent because they reference architecture specific
files.

The datadir variable becomes unused with this change, so remove it.
