The two lines above should also be removed as they're only used
in the condition to include the Python files.

I've also hit this issue and independently came up with an
alternative solution, let me know if you want me to submit it as
a patch on top of the previous fix; see below.

The Python scripts appear to be used in gitsource.sh and
tbench.sh so I guess they are needed for these kselftests
although I haven't tried to run them or do anything with them.
This is just to fix make clean.

selftests: amd-pstate: fix TEST_FILES

Replace TEST_GEN_FILES with TEST_FILES to avoid having them deleted
when doing a clean. Also fix the way the architecture is being
determined as they should also be installed when ARCH=x86_64 is
provided explicitly. Then also append extra files to TEST_FILES and
TEST_PROGS with += so they don't get discarded.
