Subject: [PATCH] Makefile.in: enable --docdir= parameter to be working

  Previously, the Ghostscript was using custom path to the documentation
  (as docdir=$(gsdatadir)/doc). This was causing that value of --docdir=
  parameter of ./configure was accepted, but not used at all.

  This commit fixes this issue, by using docdir=@docdir@@VERSIONED_PATH@
  instead. However, as a side effect this results in default path for
  documentation to changed to this (with --prefix=/usr):

    /usr/share/doc/ghostscript/<version>/

  To stay backward compatible, a symlink is automatically created to
  point from the old location (/usr/share/ghostscript/<version>/doc) to
  the new location.

  NOTE: Trying to fix this issue with the location of documentation
        staying as it was would require some hacking inside the Autoconf
        itself, which is not desirable.
