As you suspect the problem to be specific to powerpc, I can do

git bisect start -- arch/powerpc

You said that powerpc-5.13-1 is bad so you can narrow the search I think:

git bisect bad powerpc-5.13-1
git bisect good 887f3ceb51cd3~

This problably means that the step is at a commit which is prior to the first bad commit you 
identified at previous step. If you narrow the bisect as explained above, it shouldn't happen unless 
git decides it needs to descend a branch to a merge point. In that case just do 'git cherry-pick 
--abort" and go without the fix.

Note that once you have cherry picked the fix and tested the result, you have to apply the result to 
HEAD~ (the commit before the cherry-pick).
- git bisect good HEAD~
- git bisect bad HEAD~
