10.5 and gcc8 x86-64 ok but ppc bails with dlerror

[Sergio Had]

You should not need gcc8. I had gcc11 working on 10.5 ppc (and ppc64 too). I have seen people using gcc13 on 10.5 ppc following my instructions from the PR.

What is the point of gcc8?

You build gcc10-bootstrap and then use it to build gcc13. Nothing else needed in between.
