• problem identified for openSUSE as per OBS status
  https://build.opensuse.org/package/show/openSUSE:Factory:PowerPC/MozillaFirefox

• problem also reported in gentoo for version 75 as per
  https://bugs.gentoo.org/717830

Expected results:

build success

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Once "someone" writes the big endian support, this should "just work." It builds fine on ppc64le.

I think this is the same issue I have encountered for s390x. Some guidance on how to solve this can be found here: https://bugzilla.mozilla.org/show_bug.cgi?id=1618776

This should be fixed by bug 1628772, which included authenticator 0.2.12 and https://github.com/mozilla/authenticator-rs/commit/1b1be8f6824ca925d3f434568b7baec559a10ddb

Does it work on Firefox 77 or later?

Yes that build now with Firefox 77 as per https://build.opensuse.org/package/live_build_log/mozilla:Factory/MozillaFirefox/openSUSE_Factory_PowerPC/ppc64

rstewart, can you mark this bug as fixed and make it depend on bug 1628772 which fixed it
