 I have been long saying that Pythons are broken for `+universal` on PPC,
 and that been ignored, because ''no one cares''. Well, it is also broken
 on Intel:
 {{{
 clang: error: clang frontend command failed with exit code 70 (use -v to
 see invocation)
 Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
 Target: i386-apple-darwin12.6.0
 Thread model: posix
 clang: note: diagnostic msg: PLEASE submit a bug report to
 http://developer.apple.com/bugreporter/ and include the crash backtrace,
 preprocessed source, and associated run script.
 clang: note: diagnostic msg: Error generating preprocessed source(s) -
 cannot generate preprocessed source with multiple -arch options.
 make: *** [Modules/signalmodule.o] Error 70
 make: *** Waiting for unfinished jobs....
 }}}

 I actually have fixed all Pythons locally to build as universal. Tested
 for ppc+ppc64 on Leopard, but presumably gonna work on any system for
 Intel.

 I wanna avoid a situation when my PR is just closed (instead of advising
 me a better way to do it, where needed), like last time with a fix for
 Python LTO on PPC.
 If there is an interest in having this fixed, I can open a PR – and
 request for help to check it (it is not the case where I am sure
 everything works correctly and optimally – but at least it does work,
 unlike existing universal).
