    build: Change the install location of libgc
    
    A garbage collector called Boehm GC also build a library called
    `libgc` and installs it in `libdir`.
    
    To avoid any issue with this library, the installation of our
    `libgc` library has been moved to `pkglibdir`.
    
    The GObject introspection files have also been moved to `pkglibdir`
    and `pkgdatadior`.
