Source: mozjs78

Usertags: armel armhf

mozjs78 fails to build on armhf & armel.

I have little interest in working on this bug myself. I only stumbled
across this bug because I applied a build fix needed by Debian's
switch to Python 3.11. mozjs78 has been End of Life since October 2021
and is only still in Debian because Cinnamon hasn't switched to
mozjs102 yet.

By the way, 0ad has an embedded copy of mozjs78 and still builds on
armhf so maybe it includes a fix or a workaround for this build
failure.

I'm pasting the end of the build log below, but the actual build error
may have been earlier in the log.
