- Bump version and fix build.
- See CHANGES, 20200115: ${PREFIX}/share/man is for manpages, so
  remove the patch that put the manpages elsewhere, and update plist.
- When looking for qmake, look for suffixed names as well; we
  stopped using qtchooser some time ago, and adopted a qmake-qt5.
  Linux hosts do this with a check, we'll just `true` it in.
- Pull in an upstream patch to warn when there is no qmake;
  massage it to look for suffixed qmakes as well.
