Adjust JIT target triple on OS X to match the current architecture.

Browse Source 
For OS X builds, we generate one version of config.h but then build for
multiple architectures.  This means that the LLVM_HOSTTRIPLE setting may have
the wrong architecture.  Adjust it dynamically to match the current
architecture.  <rdar://problem/12715470>
