I really hope making symlinks into the kernel source isn't necessary. I
haven't experienced build failures with these tests. How are you
building them?

I usually do something like (on a x86 build host):

$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux- ppc64le_defconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux- headers
$ make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux- -C tools/testing/selftests/powerpc/

without issue.
