OK.

You clone the Git repository at
https://git.buildroot.org/buildroot-test/, add new .config files in
web/toolchains/configs/, and reference them in
web/toolchains/configs/toolchain-configs.csv, and then send patches on
the Buildroot mailing list, as usual.

Yes, we can. In this case, just provide me the base Buildroot
configuration for those targets, and I'll build the toolchains
accordingly.

Do you want just powerpc64/glibc and powerpc64el/glibc, or are there
other interesting C libraries supporting powerpc64 that we should test ?

We currently don't have a way of expressing interest only for powerpc64
but not powerpc. Is it fine if you get both results?
