<pre>After r371787 [0], when Rust's bindgen uses libclang, it fails with "no targets
are registered" [1].
This only happens when we build LLVM with `-DLLVM_LINK_LLVM_DYLIB=ON`.
jkorous: I'm not clear on why `LLVMSupport` was added to libclang's
CMakeLists.txt. If I remove that line, the code still compiles, and this bug
goes away. I'm not familiar with this part of the code though -- do you have
any idea what might be going on?
