I tried the attached patch and the build gets a lot further, but then
the final link fails for the same reason that I described in #1017979
(which is not a regression in mozjs102, mozjs91 has the same failure).
As a result of the final link failing, I don't know whether tests will
pass with this patch.
The next thing I'm going to try is using gcc 11 on armel as a workaround
for #1017979.
