    ====
    $make mrproper
    scripts/gcc-version.sh: [[: command not found
    
    This is on a very old host with an ancient bash as /bin/sh. But I have
    CONFIG_SHELL set and pointing to a modern bash. Something is wrong.
    
    This doesn't happen with 2.6.23
    ====
    
    Fixed using a more common string equality test.
