Is the git repository:
git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git
with current version:
commit 857cdd5320ce1f293f5dbcbec79cc8fe22b0bebf

That is somewhat surprising (unless you have modified the makefile). If I
try that same command (but the proper CROSS_COMPILE value for my cross
tools), the cross gcc is not picked up. But your example is clearly using
your cross gcc. I instead use:
make CC="${CROSS_COMPILE}gcc"
where CROSS_COMPILE is set for my cross tools:
$ echo ${CROSS_COMPILE}
arm-sony-linux-gnueabi-thumb2-
Everything builds ok, no need to make librttest.a and cyclictest individually.
I point out all of the above, because it does not seem like you have the
same source that I have, so I'm reluctant to dig any further.
