Yes. I'll check if compiling a simple program (w/o including all the system
headers we need) is enough to reason
about whether we can target i386. If the fix is not-trivial I'll revert the
change to un-break people.

Maroudas, Stephen
Could you test if CMake build of LLVM (http://llvm.org/docs/CMake.html) would
work on your platform?
You'd need to install cmake 2.8.8 and follow the build instructions.

$ mkdir mybuilddir
$ cd mybuilddir
$ cmake path/to/llvm/source/root
$ make

I'm specifically interested in the contents
of mybuilddir/lib/clang/3.2/lib/linux
