    Remove SMALL conditionals from gzip
    
    gzip has SMALL conditionals which enable building a reduced size version
    of the binary. These exist as part of the introduction of BSD licensed
    gzip in 2004 in NetBSD and appear to have been required to reach a size
    for inclusion in their install media. For more information see commits
    to gzip in the NetBSD tree on the 28th of March 2004.
    
    SMALL doesn't appear to be hooked up to our build system and
    complicates gzip quite a bit.
