Full build log available at: ​https://buildd.debian.org/status/fetch.php?pkg=ffmpeg&arch=powerpc&ver=7%3A4.2.2-3&stamp=1591807319&raw=0

For debugging purposes, there is a PowerPC machine available through the GCC Compile Farm, see: ​https://gcc.gnu.org/wiki/CompileFarm

Since I am an admin of gcc203 POWER machine, I can install packages if necessary.

Regression since when?

[John Paul Adrian Glaubitz]

I just had a look, the regression happened when ffmpeg 4.1.4 was rebuilt with libx265-176 and gcc-9.
