Describe the issue
I have spent quite some time today on abseil on powerpc (I need to debug an obscure failure in protobuf, and for that I need to ensure the bug is not caused by abseil), and got from 17 failing tests down to 4, two of which seem to be precision-related (thus not a big deal, we do not compute rocket designs).
There are two tests, however, which fail for a reason unclear to me, and it will be nice to fix their causes.
