rtapi/Submakefile:  HACK  build rtapi/sim_rtapi_app.cc with -DRTAPI
rtapi/Submakefile:  HACK  build rtapi/sim_rtapi_app.cc with -DRTAPI

from Submakefile:
+# HAAACK:
+#
+# Build objects/rtapi/sim_rtapi_app.o in Makefile as other USERSRCS,
+# but replace -DULAPI with -DRTAPI:  Makefile doesn't handle -DRTAPI
+# C++ sources

Need RTAPI build for rtapi_set_msg_handler()
