For some reason, the dynamic run-time linker finds a non-native "mach-o"
(whatever that is) when it tries to run the test program so the test program
obviously fails.

I don't know xcode so I have no idea how this came to be, but you can probably
repeat the problem by rerunning that build command line and a similar test
program and then you should be able to investigate how it comes the wrong lib
gets to be used.
