modifications by Greg Stein (comments and text changes).
* buildconf.sh: to deal with crazy/custom libtool installations, allow
the developer/package to specify the libtool.m4 location by
setting the LIBTOOL_M4 environment variable. If that isn't set,
then we use our previous method of trying to derive its location.
