    project.config: Set hooks.commit-extra-checker option
    
    This points to a script written by Simon Marchi which verifies
    that the commit's author name and email are not "xxx via sourceware",
    which happens when the commit was created via "git am" of a patch
    received via the gdb-patches mailinglist.
