makefile improvements

Using $(libdir) variable instead of $(prefix)/lib. This helps maintain
consistency between paths used in Makefile and those provided by the
build system used in spec (e.g. %_libdir).

Make sure that Makefile.inc is created before its inclusion in Makefile.
Since Makefile is already build, it's not quite obvious that configure
script needs to be run for Makefile.inc to be generated.

Fixed configure script to correctly generate datadir variable.
