Issue #14499: Fix several problems with OS X universal build support:
1. ppc arch detection for extension module builds broke with Xcode 5
2. ppc arch detection in configure did not work on OS X 10.4
3. -sysroot and -arch flags were unnecessarily duplicated
4. there was no obvious way to configure an intel-32 only build.
