Following warning is observed at link.

  powerpc-linux-ld.bfd: warning: arch/powerpc/lib/reloc.o: missing .note.GNU-stack section implies executable stack
  powerpc-linux-ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

Add -zexecstack to KBUILD_LDFLAGS in order to suppress this warning.
