The change as broken MacOS due to this bug ...

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81797

I posted build results showing the error is still present. I had a patch in the
previous version and it should apply.

This is a catch-22, I hope to start on the release process soon but things like
this add to the complexity and add to the time it takes.

Joel has stated many times in talks I have seen that we follow the architectures
GCC supports and if one is removed we remove support.

Does this mean 5.1 is the last version of RTEMS to support SPE?
Should the specific BSPs be moved to tier 4 and marked for removal?

What options are these?

Also this seems back to front to me. Should all hosts be on 9.2.0 and those that
cannot have specific versions?
