    Murder CFLAGS before gi-r-scanner sees them
    
    It seems that when CFLAGS exists in the environment the
    Makefile's version of it leaks into the shell introspection
    is running in. This causes the string to get parsed twice
    and confuses the escaped \s.
    
    Really this is a horrid hack and someone who knows more
    about autotools should find the correct way to fix it.
