    This breaks:
    Running /usr/src/gcc/gcc/testsuite/gcc.misc-tests/help.exp ...
    FAIL: compiler driver --help=target option(s): "^ +-.*[^:.]$" absent from output: "  -mfix-cortex-a57-aes-1742098 Mitigate issues with AES instructions on Cortex-A57 and Cortex-A72. Arm erratum #1742098"
    
    help.exp with help of lib/options.exp tests whether all non-empty descriptions of
    options are terminated with . or :.
