#     selftests/powerpc: Fix Makefiles for headers_install change
#     
#     Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk")
#     introduced a requirement that Makefiles more than one level below the
#     selftests directory need to define top_srcdir, but it didn't update
#     any of the powerpc Makefiles.
#     
#     This broke building all the powerpc selftests with eg:
#     
#       make[1]: Entering directory '/src/linux/tools/testing/selftests/powerpc'
#       BUILD_TARGET=/src/linux/tools/testing/selftests/powerpc/alignment; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C alignment all
#       make[2]: Entering directory '/src/linux/tools/testing/selftests/powerpc/alignment'
#       ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory
#       make[2]: *** No rule to make target '../../../../scripts/subarch.include'.
#       make[2]: Failed to remake makefile '../../../../scripts/subarch.include'.
#       Makefile:38: recipe for target 'alignment' failed
#     
#     Fix it by setting top_srcdir in the affected Makefiles.
#
