And of course after sending the mail is when I noticed this
was previously committed, then reverted in 2008, with the note:

    Unfortunately this doesn't work on old pkg-config, which made
    Requires.private completely useless.  That's fixed in 0.22, but...

Do we still need to support new libXft builds with pkg-config < 0.22?
