Firefox 85+ on -current fails build

My current slackbuild script no longer works for 85+ - compile fails at:

Anyone have adjustments to slackbuild or patches to assist with this release? My most recent successful build is 84.0.2 - the last slackbuild patch at that time was:

# https://bugzilla.mozilla.org/show_bug.cgi?id=1640982 sed -i "s|-Clto$||" config/makefiles/rust.mk

... for a rust-related issue.

(my system is -current 64bit updated to just before the recent mega rebuild)

Thanks in advance.
