It looks like this the 64-bit mode uses the 32-bit configuration file.
From configure.in:

  ## Apple Darwin / Mac OS X
  *-apple-darwin* )
    case "${canonical}" in
      i[3456]86-* )  machine=intel386 ;;
      powerpc-* )    machine=macppc ;;
      * )            unported=yes ;;
    esac

there should be an:
      x86_64-* )       machine=amdx86-64 ;;
in that "case".

that will allow to remove this from emacs/src/s/intel386.h:

#if defined (DARWIN_OS)
#ifdef _LP64
/* For Intel Mac, with CC='gcc -arch x86_64'.  */
#define NO_ARG_ARRAY
#endif
#endif

there shouldn't be any _LP64 checks in that file.
