linking of libraries in qt3-tools fails due to a missing libstdc++.la.

A workaround is to copy it from /usr/lib into the buildlink directory.

>How-To-Repeat:
build qt3-tools on Slackware 9.

>Fix:
I think fake libtool archive magic is required.

fwiw, my /usr/lib/libstdc++.la looks like this:


# libstdc++.la - a libtool library file
