Thanks a lot for your contribution. Believe it or not, but after some
many months, I finally took the time to review and apply your patch.

However, I did quite a few changes:

 - I kept only the host variant of the package. Indeed, my
   understanding is that agent-proxy is meant to be executed on the
   developer workstation to de-multiplex the kgdb traffic from the
   console traffic. Therefore it was not clear why a target variant was
   needed. Of course, if additional justification/explanation is given,
   the target variant can be re-added via a follow-up patch.

 - Addition of an entry in the DEVELOPERS file

 - Addition of a .hash file with the hash of the tarball and hash of
   the COPYING file.

See below for some other comments.

This was not correct: the license is GPL-2.0 only.

This had not effect since AGENT_PROXY_INSTALL_STAGING is not set to
YES. But anyway, I dropped this since I dropped the target variant;

$(HOST_CONFIGURE_OPTS) not needed here, and we want the full
destination path as the last argument, i.e $(HOST_DIR)/bin/agent-proxy.

Once again, thanks a lot for this contribution!

Best regards,

Thomas
