I think the answer here depends on where you prefer to get your GCC binaries from.
As far as the upstream GCC project goes (of which this is the mailing list) the most modern GCC release supporting -mcpu=grace is GCC 14.2 that was made a couple weeks ago: https://gcc.gnu.org/gcc-14/
I expect the various Linux distributions will be packaging it for their users soon. If you are comfortable building your own compilers from source you can take the GCC 14.2 sources and build the cross-compilers and native compilers yourself.
Thanks,
Kyrill
