+universal vs the buildbot

[Ryan Stonecipher]

Some ports have +universal as a default variant.
When such ports have "big" dependencies such as qt4-mac, gcc4x, or
atlas they take hours to build and install.
The buildbot makes installing default single-architecture binaries painless.
Could the buildbot be adapted to also provide +universal binaries with
default universal architectures for +universal-by-default ports and
their dependencies?
