[issue23670] Modifications to support iOS as a cross-compilation target

Alex - The usual cause for that problem isn't regrtest (at least, not directly). The cause is one of the tests in the suite spawning a subprocess. Due to the way the test harness works, when the test suite forks/spawns a  subprocess (e.g., to run a network server or a multiprocess worker), the fork causes the a second version of the test suite to start, rather than starting the server subprocess.

I've attached a patch for 3.5.1. This includes a patch to work around Issue22625; the patch is definitely suboptimal, but it lets a build come to completion. What is really needed (as requested on python-dev) is some help working out how to fix Issue22625 properly.
