    Make distribution tarball compression format configurable

    By default, bzip2 compression is selected (which is what has been used
    till now). Additionally, by setting the TAR_COMP make variable to one of
    the values "bzip2", "gzip", or "xz", an explicit compression format can
    be requested for the distribution tarballs. For instance, invoking

      make TAR_COMP=xz sdist-ghc

    will result in a tarball `./sdistprep/ghc-7.9.20140226-src.tar.xz`

    Individual sdist-foo targets

    so that one can build a source distribution without downloading the
    windows tarballs.
