I mentioned this briefly on cygwin-patches during the review of the fix
for a deadlock when running under emulation on ARM64 hosts, but I wanted
to discuss it more thoroughly here now that that is merged.
It seems like it would be useful, perhaps for stats tracking purposes like
MSYS2 does [1], to indicate when Cygwin is running under emulation in
uname. When i686 Cygwin was supported, there was a `-WOW64` tag appended
to the sysname field (uname -s) when it was running under WOW64, so it
seems to make sense to me to do something similar (say, appending
`-ARM64`).
We already collect some limited, anonymized stats from our setup program
(see [1]), which show that ARM64 hardware is still rare.
