[Buildroot] [git commit] package/gdb: prevent gdbserver being selected for or1k builds

[Arnout Vandecappelle <arnout@mind.be>]

commit: https://git.buildroot.net/buildroot/commit/?id=d16db6d8a405c8410f4e892a3993686a3269bdc2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

There is currently no version of gdbserver for or1k. Until this
is implemented we will prevent both the direct and indirect
selection of gdbserver for or1k builds. In practice this means
that 'cross gdb for the host' cannot be selected and that
'full debugger' must be automatically selected for the gdb target
package.

This partially reverts commit 991b7b990ad8cd4a37564cd91d5bb0ee7e1e9f11
which claimed that gdbserver for or1k was already supported before
version 8.3. That is not true - the commit that adds gdbserver support
for or1k [1] was only merged for version 12.1, which hasn't been
integrated in Buildroot yet.

Without that support, the build of gdbserver fails with
