    config, aarch64: Use a more compatible sed invocation.
    
    Currently, the sed command used to parse --with-{cpu,tune,arch} are
    using GNU-specific extension (automatically recognising extended regex).
    
    This is failing on Darwin, which defualts to Posix behaviour.
    However '-E' is accepted to indicate an extended RE.  Strictly, this
    is also not really sufficient, since we should only require a Posix
    sed.
    
    gcc/ChangeLog:
    
            * config.gcc: Use -E to to sed to indicate that we are using
            extended REs.
