For memtester, debug mode says:
DEBUG: not using configure, so not adding the default universal variant
The default universal variant can only work if the port uses a configure
script (or xcodebuild). Exactly what needs to be done to make a port
build universal varies greatly, but usually boils down to somehow
getting the build system to use the right flags:
You add the code to make it do this in a universal variant.
