We need more storage!

We need more computational power, especially in non-Intel-compatible
architectures (ARM 32 and 64-bit, and MIPS). Also, if we did something
like this, we would not want to build from every commit. Perhaps every
push. And only for master; branches like core-updates tend to collect
untested patches for a while before we start trying to build the branch.
There's no point trying to build every package from branches in that
state.
