Unfortunately there is no easy way to do this without copying. In addition to the default set of warnings, add -Wno-sign-compare to disable that warning. That's because Makefile.extrawarn does some extra steps to disable some -Wextra warnings unless W=3D2 or W=3D3 are used. That's the only one that's needed for Coresight, so disable it.
