Prior to commit 70a6fcf328 ("[sparc] unify 32bit and 64bit string.h"),
__HAVE_ARCH_STRLEN was defined in both of string_32.h and string_64.h
It did not unify __HAVE_ARCH_STRLEN, but deleted it from string_32.h
This issue was reported by the kbuild test robot in the trial of
forcible linking of $(lib-y) to vmlinux.
