[New-bugs-announce] [issue43782] Failure to build from source on ppc64le on ubuntu xenial

[Anthony Sottile]

New submission from Anthony Sottile <asottile at umich.edu>:

I realize this is unlikely to be a helpful report, but something that changed between 3.9.3 and 3.9.4 has caused the build to break on (admittedly a strange platform) ppc64le


I attached the build log (zipped because otherwise it's too big ?)

The live URL is here: https://launchpadlibrarian.net/532585040/buildlog_ubuntu-xenial-ppc64el.python3.9_3.9.4-1+xenial1_BUILDING.txt.gz

Probably the most relevant part of the bug report is this bit, though I'm guessing so I don't really know what is useful and what is not.

```
