Comment (by h.rayflood@…):

 asan_iossim_dynamic/x86_64/libcompiler_rt.dylib is built for x86_64.[[BR]]
 but xcode-4.* don't have x86_64 libc++.

 on leopard, asan compiler_rt is disabled by leopard-no-asan.patch.[[BR]]
 so, leopard-no-asan.patch is needed with xcode-4.* too.

 and, leopard-no-asan.patch is pretty bad.[[BR]]
 asan_iossim_dynamic and ubsan_iossim_dynamic is removed from
 Configs.[[BR]]
 but not removed from RuntimeLibrary.darwin.Configs.

 I think this misstake causes #47241 "cp:
 asan_iossim_dynamic/libcompiler_rt.dylib: No such file or directory"
