[PATCH] [BUILDROBOT] RX: Mark unused argument

[Jan-Benedict Glaw]

Hi!

I noticed that rx_handle_func_attribute() doesn't use it's `args'
argument any longer since DJ removed it's a gcc_assert() using it.
See eg. this build:
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=372376

Silence the warning. Ok for mainline?
