FWIW I think the new rust does build Firefox.
I ran into the librsvg issue as well but opted to do
"pkg_rolling-replace -rsuv -X librsvg"
to keep the old librsvg binary package I had and pkg_rr finished all my
other packages including Firefox.

Since we are in a pkgsrc freeze I think it is safer to just revert
the aarch64 specific change than to cause churn and versions going
backwards by downgrading rust. Assuming the revert solves the problem
of course.
