ARMv5 and ARMv6 aren't supported.  In theory they could be to some extent, but
they lack adequate concurrency-related instructions (atomic insns, mem fences)
and the overall hassle-to-benefit ratio doesn't seem worth it.  ARMv7 is
ubiquitous now -- can't you use that?

No, that's not the case.  ARMv8 (that is, 8.0) is supported in both 32 and 64
bit modes (that is, for both "arm" and "aarch64").
