    Fix clean for autooled modules with srcdir != buildir (GNOME bug 597954)
    
    autotools.py skip_clean incorrectly checks for the existence of the makefile
    in the srcdir, not the build dir (where it will actually be created by autogen.sh)
    This causes 'jhbuild build --clean' to not clean when srcdir != builddir
