I think GDB's "target" is always the OS kernel, not the OS itself.

The distinction FSF asks for is between the GNU/Linux as a whole
system, which includes all the main applications and libraries, and
Linux as the bare-bones OS.  GDB targets the latter, not the former.

That's a mistake, IMO.  There's no need for GNU here.
