expat buildconf.sh,1.9,1.10

Update of /cvsroot/expat/expat
In directory sc8-pr-cvs1:/tmp/cvs-serv22950

Modified Files:
	buildconf.sh 
Log Message:
Patch submitted by Joe Orton <[email protected]> with additional
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.
