[Buildroot] [git commit branch/2021.02.x] package/gdb: improve gdb version choice comment

commit: https://git.buildroot.net/buildroot/commit/?id=a04fd7a50528a4053f3ea7e19dddaabfb617ff82
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

The comment has been introduced by commit [1] where the latest
gdb version has been used when cross-gdb is not enabled.

But since then the gdb package doesn't use the latest gdb version when
cross-gdb is not enabled. It's the "stable" version.
