The "fix" is:

  --- a/shells/mksh/files/funcs.c
  +++ b/shells/mksh/files/funcs.c
  @@ -3240,9 +3240,6 @@ ptest_error(Test_env *te, int ofs, const char *msg)

   #define ULIMIT_M_IS_RSS
   #endif
  -#if defined(ULIMIT_M_IS_RSS) && defined(RLIMIT_AS) && (RLIMIT_RSS == RLIMIT_AS)
  -#undef ULIMIT_M_IS_RSS
  -#endif
   #endif
   
   #if !defined(RLIMIT_AS) && !defined(ULIMIT_M_IS_VMEM) && defined(RLIMIT_VMEM)

i.e. just because macOS has "#define RLIMIT_RSS RLIMIT_AS" in its
sys/resource.h for compatibility, don't remove -m support.
