[Buildroot] [PATCH] package/gdb: gdb 12.1: enable host-gdb and gdbserver support for or1k

[Romain Naour]

The gdbserver support for or1k is available since 12.1 release, since
commit [1]. Restrict the gdb version choice for or1k to 12.1 for
simplicity. Also enable host-gdb to connect to the gdbserver on the
target.
