It goes without saying that this only works if your machine actually
has 32-bit ARM instructions. For instance, the ARM VMs at Scaleway
have no 32-bit support.

aarch64 support for Go is there in 1.13 but crashes as soon as it gets
a signal. Someone needs to switch the runtime to use TLS instead of a
CPU register, because receiving a signal clobbers its value. This will
hurt performance a bit, unfortunately.

The master bug is https://github.com/golang/go/issues/30824.
