commit ebb7aca66785730737bc739624006e55d43dfe1b
Author: Chris Wilson <chris at chris-wilson.co.uk>

    Suggest where to find xorg-macros in case it's missing
    
    [Modified version of U. Artie Eoff's commit to remove the duplicated
    string. The paraphrased commit message is repeated below for clarity.]
    
    xorg-macros is often package under an unusual name, so provide some
    clues as to what name to try on the user's distribution. Installing
    build-deps would be just too easy...
    
    Also include a check for the existence of the XORG_DRIVER_CHECK_EXT
    macro, otherwise configure might continue in spite of the missing macro
    and cause obtuse syntax errors.
