patch 1 - don't require COPYING if LGPL used

[Bonzini]

This patch distributes COPYING.LESSER automatically, and no longer
requires COPYING if COPYING.LESSER or COPYING.LIB is found.

Since I was at it, I modified common_files to also distribute shtool.

2002-05-03      Paolo Bonzini  (address@hidden)

         * automake.in (check_gnu_standards): accept in --gnu
         mode that COPYING is absent if one of COPYING.LESSER or
         COPYING.LIB is there.
         (common_files): Automatically distribute COPYING.LESSER
         and shtool
         * automake.texi (Gnits): document this.
