OS X: detect clang and build for x86 target only.
Newer versions of Xcode / OS X don't support PPC code anymore and replace gcc with clang. When clang is detected assume we want to build for the default architecture only and change the minimum OS X version to 10.5. Change-Id: I5843fa9bb3d957ec6f0a537e857608ad99c31517
