Needs to specify i386 in the CMAKE_C_FLAGS and CMAKE_CXX_FLAGS on 64-bit OS

[GoogleCodeExporter]

On the newer version of OS X, gcc's default arch is x86_64. This causes a 
problem—because the 
current LLVM and clang's build arch is i386. But because ccons never specifies 
the arch on OS X, it 
builds incompatible binaries (i.e. ld complains that no x86_64 LLVM libraries 
are available).

The diff attached below specifies arch i386 in CMAKE_C_FLAGS and 
CMAKE_CXX_FLAGS which 
should mitigate the problem. Am not sure if this would break the build on other 
platforms, though.

Hmm, I guess we should be getting that information out of llvm-config 
--host-target

I've committed a change to CMakeLists.txt that uses llvm-config to get the host 
target that is used when 
building ccons. I believe this should fix the issue you were seeing.
