qrupdate fails to build if libtool port is active

[ned@…]

The Portfile for qrupdate 1.1.1 edits src/Makefile to change the call to "ar -cr" into a call to "libtool -o". However, that usage of libtool only works with the system libtool in /usr/bin, not with the Macports libtool (which is a later version of GNU libtool).

So if you have the Macports libtool port active, you get

libtool: unrecognized option: -o

The workaround is to deactivate the libtool port before building qrupdate.

However, this should be fixed to allow usage with the Macports libtool port active.
