This recipe uses some convoluted methods to ensure the build is using the right flags but they don't appear to be needed anymore. No need to prepend HOST_CC_ARCH/TOOLCHAIN_OPTIONS via CFLAGS as the Makefile picks up CC from the environment and that includes these options. No need to append the default CFLAGS as their special options are actually in CPPFLAGS.

The recipes-rt recipes provide package and image recipes for using and testing the PREEMPT_RT kernel. The core-image-rt*.bb images are minimal images with a couple extra packages, including rt-tests. In order to build the image with the linux-yocto-rt kernel, be sure to include the following line in your local.conf, bblayers.conf, or your $MACHINE.conf.
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"
If you are creating a new BSP which should use linux-yocto-rt by default, use the line above in the $MACHINE.conf in your BSP layer, and specify the following in a linux-yocto-rt bbappend recipe:
COMPATIBLE_MACHINE_$MACHINE = $MACHINE
