: 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

: cross-debugger is simply not utilized as part of a buildworld.
But MACHINE_ARCH is set correctly during the build of gdb when you've
set TARGET_ARCH to build the rest of the world you need to build gdb
with. Or am I missing something?
