Sorry, I don't understand where that limitation comes from.

The gdb remote protocol is standardized.  It's plain ASCII, and I
can't see how it would be affected by the choice of toolchain.  There
are plenty of third-party gdb servers that are not only built by
different entities, but the server isn't even built from gdb sources.

As long as as the gdb server and client versions are compatible (e.g.
they're using the same protocol) they should work fine.

Have you seen protocol failures betwee gdb server/client due to the
fact that a different toolchain was used to build them?  If so, my
understand is that's a bug and should be reported to the gdb
maintainers.
