    pipeline: tidy up definition of *END defines
    
    There is some fairly awkward #ifdefing to determine which vertends,
    fragends and progends are available at build time. This patch
    consolidates the #ifdefing of vertend, fragend and progend defines to
    make for slightly easier reading.
