[PATCH 0/3] Clean up PowerPC selftest stderr output

[Benjamin Gray <bgray@linux.ibm.com>]

There are several messages being logged to stderr when building the PowerPC
selftests:

  $ make -j$(nproc) O=build -C tools/testing/selftests \
    INSTALL_PATH="$PWD"/out/selftests TARGETS=powerpc install > /dev/null

This series fixes or silences them to make any legitimate build warnings more
apparent.

  selftests/powerpc: Use CLEAN macro to fix make warning
