When you run the test suite are you using FlexiBLAS with OpenBLAS
selected? I assume so.

Is your Ubuntu system x86-64?

In your fntests.log file, all 4 failures are because the difference is
slightly out of the test tolerance.

I think the gammainc.m test tolerances were chosen empirically, and they
have been increased in the past (https://savannah.gnu.org/bugs/?53437).

Cc'ing Colin to comment on the camlookat.m test results and tolerances:
