I tried Alex's patch on top of RSB 
bfed51462eafcb6a5102a2d6d80b233f3c6ef635 for RTEMS 6 and microblaze:

almalinux 8.7: OK           [gcc (GCC) 8.5.0]
debian 11: OK               [gcc (Debian 10.2.1-6) 10.2.1]
fedora 37: OK               [gcc (GCC) 12.2.1]
opensuse-leap 15.4: OK      [gcc (SUSE Linux) 12.2.1]
ubuntu 22.04: OK            [gcc (Ubuntu 12.1.0-2ubuntu1~22.04) 12.1.0]

With FreeBSD I cannot help, sorry. Also, the above containers use the 
latest OS versions. I did not test older ones. Moreover, Opensuse 15.4 
does not use gcc 12 by default but a much older compiler.

*Without* Alex's patch these builds fail on Ubuntu and Fedora when 
building building microblaze-rtems6-gdb-11.2-x86_64-linux-gnu-1 with the 
following error:
