For the record, we have buildbots for AArch64 Linux here:

They're red at the time of writing, but we're actively maintaining
them and will bring them back to green asap.

Please let us know if there are any other requirements or if we should
be testing other configs as well (at the time being we're only
compiling with clang, is gcc also a must?).
