On aarch64, neon will not be present in /proc/cpuinfo, instead asimd is there. Previously, we'd fall back to arm when running with a 32-bit userland, even though armv7 is perfectly appropriate in this case.

This would then run into the issue described in rust-lang/rust#58414 with "CP15 barrier emulation".

This PR fixes that.
