This failed awhile ago, and I didn't report assuming someone else probably had the same issue, and I still suspect that, but I couldn't find a bug report for 7.1. If not, better late than never. Thanks.

The problem only affects the +vnc variant. The --enable-vnc-png option ​was renamed to --enable-png.

I was working on this without realizing someone else already submitted a PR, which just got merged in [1ede2f6ee68bbf1700bd792c1a31c1b2a2e29c9a/macports-ports].

qemu: Adjust new PNG configure argument handling

Since --enable-png is now a global arg, make sure we turn it off
globally and enable it only where we're intending to use it (and adding
the libpng dependency).
