Subject: [PATCH] lib.systems: force qemuArch to "aarch64" on aarch64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

qemu architecture names are fixed — we're using uname here just
because it's more likely to be correct than CPU name (see e.g. POWER).
This means that aarch64 is always called aarch64, even on Darwin where
uname reports arm64.

Fixes: 61582c704327 ("lib/systems: use Darwin architecture names for `config` and `uname`")
