Subject: [PATCH] tools/libtool: bootstrap to local gnulib source

Using the local gnulib source during bootstrap
allows for fine-grained control over the macros
and source files for use with libtool
but part of gnulib instead of libtool,
without having to wait for a release
or deal with gnulib as a git submodule.
