All of the rt-tests patches that OE has been carrying have been upstreamed or superceded by changes in the v0.94 release. Adjust SRC_URI to point to canonical upstream git repo, instead of a development tree. There was a notable change upstream that required slight reworking of the recipe. rt-tests now joins other kbuild-inspired projects by making use of a CROSS_COMPILE flag to indicate the compiler prefix. Previously TOOLCHAIN_OPTIONS were conveyed via $CC directly, however, this does not work with CROSS_COMPILE. Workaround this by both specifying CROSS_COMPILE, and feeding the rt-tests build system the proper $(HOST_CC_ARCH)$(TOOLCHAIN_OPTIONS) via $CFLAGS.

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
