[epiphany] Use more AX_REQUIRE_DEFINED

    Use more AX_REQUIRE_DEFINED
    
    Gabriel was missing the AX_GENERATE_CHANGELOG macro because he hadn't
    built m4-common in a while, and you wind up with a notoriously terrible
    error message if AX_REQUIRE_DEFINED is missing.
    
    (This does nothing to help the poor souls who do not yet have
    AX_REQUIRE_DEFINED installed....)
