Well, my personal experience (and I've heard this experience from
several other people has well) is that to avoid problems the gdbserver
version you're using should be the same as the cross-gdb used to
connect to this gdbserver. Therefore, it makes sense for a toolchain to
provide both cross-gdb *and* gdbserver, or none of them, but it doesn't
make much sense to offer just cross-gdb without a gdbserver. As I was
mentioning before, Linaro toolchains, Sourcery CodeBench toolchains do
that.

Best regards,

Thomas
