Daniel Dunbar cdf9bf7048 make/clang_darwin: Tweak CheckArches function to force the integrated-as and use 
the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.
