#     sparc: revive __HAVE_ARCH_STRLEN for 32bit sparc
#     
#     Prior to commit 70a6fcf3283a ("[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.
#     
#     Fixes: 70a6fcf3283a ("[sparc] unify 32bit and 64bit string.h")
