Add new port devel/qconf:
QConf allows you to have a nice configure script for your qmake-based
project. It is intended for developers who don't need (or want) to
use the more complex GNU autotools. With qconf/qmake, it is easy
to maintain a cross-platform project that uses a familiar configuration
interface on unix.
PR: based on ports/151028
