 I have built those myself on 10.5.8 and 10A190. In Macports environment,
 of course. I have used gcc10–gcc12, they all work on Leopard, SL PPC and
 SL Rosetta.

 Not sure if we have any case for gcc8–gcc10 at all, and certainly not for
 parasitic libgccs (`gcc10-bootstrap` is the only gcc10 that is essential).
 We ''do'' want to keep `gcc11` for the time-being, since gcc12 has
 occasional failures, see discussion here: https://github.com/iains/darwin-
 toolchains-start-here/discussions/41
