#     powerpc: Adjust adding stack protector flags to KBUILD_CLAGS for clang
#     
#     After fixing the HAVE_STACKPROTECTER checks for clang's in-progress
#     per-task stack protector support [1], the build fails during prepare0
#     because '-mstack-protector-guard-offset' has not been added to
#     KBUILD_CFLAGS yet but the other '-mstack-protector-guard' flags have.
#     
#       clang: error: '-mstack-protector-guard=tls' is used without '-mstack-protector-guard-offset', and there is no default
#       clang: error: '-mstack-protector-guard=tls' is used without '-mstack-protector-guard-offset', and there is no default
#       make[4]: *** [scripts/Makefile.build:229: scripts/mod/empty.o] Error 1
#       make[4]: *** [scripts/Makefile.build:102: scripts/mod/devicetable-offsets.s] Error 1
#     
#     Mirror other architectures and add all '-mstack-protector-guard' flags
#     to KBUILD_CFLAGS atomically during stack_protector_prepare, which
#     resolves the issue and allows clang's implementation to fully work with
#     the kernel.
