Why are we installing libtool files now?

Sun Jun 4 21:59:00 GMT 2006

I noticed that with a full build (including all of GCJ and libgcj),
we now install a bootload of libtool files into $PREFIX/share:
 .../share/libtool/libltdl/COPYING.LIB
 .../share/libtool/libltdl/Makefile.am
 .../share/libtool/libltdl/Makefile.in
 .../share/libtool/libltdl/README
 .../share/libtool/libltdl/acinclude.m4
 .../share/libtool/libltdl/aclocal.m4
 .../share/libtool/libltdl/config-h.in
 .../share/libtool/libltdl/config.guess
 .../share/libtool/libltdl/config.sub
 .../share/libtool/libltdl/configure
 .../share/libtool/libltdl/configure.ac
 .../share/libtool/libltdl/install-sh
 .../share/libtool/libltdl/ltdl.c
 .../share/libtool/libltdl/ltdl.h
 .../share/libtool/libltdl/ltmain.sh
 .../share/libtool/libltdl/missing
Is this really necessary? If so, I'd like to understand why?
