 `qmake` currently has multiple issues that ports have to work around (as
 brought up in tickets #38272 and #38250):

 - `qmake` isn't [https://trac.macports.org/wiki/UsingTheRightCompiler
 UsingTheRightCompiler] (cf. comment:ticket:38250:1)
 - `qmake` doesn't handle `-arch` flags properly (cf.
 comment:ticket:38250:2)
 - `qmake` doesn't handle the `--disable-dependency-tracking` flag properly
 (cf. comment:ticket:38272:1)

 And I'm sure there's other things that could be done with a `qmake`
 portgroup, too.
