    cogl/configure.ac: AC_SUBST an empty MAINTAINER_CFLAGS
    
    For compatibility with the way we build Cogl as part of Clutter we now
    substitute an empty MAINTAINER_CFLAGS variable. When building Cogl
    standalone all our extra CFLAGS go through COGL_EXTRA_CFLAGS so the
    separate MAINTAINER_CFLAGS aren't used, but automake will get confused
    if a substitution isn't made.
