Please don't upload packages to the archive with NO_PNG_PKG_MANGLE set,
optimizing PNGs isn't the only thing it does. Maybe we should have a
second flag just for turning off PNG optimization, but the better answer
for many (admittedly, not all) packages is to split PNGs into arch-indep
packages, so they only build on i386.
We do have faster ARM buildds in the pipe as well, though they're still
in a testing phase right now, but they'll be online Soon(tm), so let's
see how that helps out with some of the awful.
