    Add separate m4 dir to avoid intltool/libtool splattering over gnulib
    
    If no generic -I m4 directory is listed, libtool & intltool will
    splatter their files all over those belonging to gnulib. This gives
    wierd, unpredictable build errors depending on whose file was copied
    over most recently.
    
    * Makefile.am: Add -I m4 flag
