I disagree. The fact that gdb is not a cross-tool in the buildworld
sense of the meaning is because we don't need gdb to cross-build world.
This does not mean that gdb cannot be a cross-tool from a developers
point of view. In fact, it's really handy to be able to debug a kernel
remotely when the debugger doesn't run on the same architecture as
the kernel. I for one do not want to have 2 machines per architecture
for the only reason that I want to debug a kernel remotely. So, I made
some changes to work towards that goal. I see no problems or harm,
especially since I'm not misusing TARGET_ARCH. The ability to build a
cross-debugger is simply not utilized as part of a buildworld.
