Yes, but:

1) Typically the binary being debugged has to be passed explicitly as
   gdb argument, it's not automatically "inferred" by gdb. So having it
   in output/build/foo-<version>/somewhere/ or elsewhere doesn't make a
   huge difference.

2) If for convenience reasons we want to make all binaries with
   debugging symbols easily available, then the long term solution we
   have been discussing for a while is to install all packages to
   STAGING_DIR. So basically I'm more for extending STAGING_DIR to
   contain binaries rather than to create a partial copy of STAGING_DIR
   in HOST_DIR/lib/debug.
