#     selftests: powerpc: Fix warning for security subdir
#     
#     typing 'make' inside tools/testing/selftests/powerpc gave a build
#     warning:
#     
#     BUILD_TARGET=tools/testing/selftests/powerpc/security; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C security all
#     make[1]: Entering directory 'tools/testing/selftests/powerpc/security'
#     ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
#     make[1]: *** No rule to make target '../../../../scripts/subarch.include'.
#     make[1]: Failed to remake makefile '../../../../scripts/subarch.include'.
#     
#     The build is one level deeper than lib.mk thinks it is. Set top_srcdir
#     to set things straight.
#     
#     Note that the test program is still built.
