Log Message:
Change the default for BUILDLINK_DEPMETHOD.qt3-tools from "full" to \ 
"build",
without affecting packages that are currently using it.

Packages which previously didn't set BUILDLINK_DEPMETHOD to neither \ 
"full" nor
"build" now set it to "full", but should be checked whether \ 
they really need it
(comment added).  Packages which previously set it to "build" now \ 
don't set it
anymore.

Ok by jlam, wiz.
