[mm-common/gmmproc-refactor: 1/2] Adapt to refactored gmmproc.

[Krzesimir Nowak <krnowak src gnome org>]

commit ad6997640d58733f0e378f2ef14d32d01a9091d4
Author: Krzesimir Nowak <qdlacz gmail com>
Date:   Mon Jul 2 22:55:56 2012 +0200

    Adapt to refactored gmmproc.
    
    * build/generate-binding.am: Some of the variables are not needed
    anymore (like the one involving m4), but some other had to be added
    (like include paths for perl or type info files).
