Subject: Make bootstrap easier on Solaris.

* bootstrap: Add GNULIB_SRCDIR.  Useful when a wrapper script
gnulib-tool exists earlier on the path to work around /bin/sh
failure in parsing $GNULIB_SRCDIR/gnulib-tool.

Signed-off-by: Eric Blake <ebb9@byu.net>
(cherry picked from commit 90a0154d6ef1effe64c199eb61a06430199aaa91)
