[Bug 1923505] [NEW] thunderbird 78.9.0 FTBFS on ppc64el

[Olivier Tilloy]

Public bug reported:

The build hangs forever when compiling the webrender rust crate (see
https://launchpad.net/ubuntu/+source/thunderbird/1:78.9.0+build2-0ubuntu3/+build/21368163).
I'm attaching the full build log for future reference.

This happens when building with rustc 1.50.0+dfsg1+llvm-0ubuntu4 and 1.50.0+dfsg1+llvm-0ubuntu5 (the latter is the version currently in the hirsute release pocket).
The build completes when building with rustc 1.50.0+dfsg1+llvm-0ubuntu2.
