Title: Install header-only pkgconfig file to generic lib/

The previous version assumed that we had libraries, and thus always installs the .pc file in the multi-arch library directory. However, we now have modules which does not have a library, but whose header files still need to be located. Since the lib/ directory is usually in the pkgconfig search path, it is natural to put them there.
