Thanks, Brad. This is a fairly big port and I'm reluctant to enable it
for arm64 without reports on the test suite (`make test`) and runtime.
A convenient way to test runtime (if you don't mind the assets that are
downloaded into ~/.local/state/BAR) is running
$ beyond-all-reason
and then testing something from "Scenarios" (button on the left). The
first one, "Fortress Assault" would be good one to just load up and give
some commands to the units.
Benchmarking can be done in the scenarios at the bottom, "Benchmark
BAR" and "Benchmark pathfinding" will give some times for rendering and
don't require input.
