Thank you for the detailed reply. It sounds to me like this will eventually have
to get solved anyway, so we could move ahead without clone() on loongarch,
and just not have support for Chrome until this is fully solved.

As both the glibc and musl ports are being proposed for inclusion right
now, we should try to come to a decision so the libc ports can adjust if
necessary. Adding both mailing lists to Cc here, the discussion is archived
at [1].
