Possible? Sure. Is this supported in the current build system? No.

Not that I'm aware of.

To do it you would basically need to grab the LLVM C export list that llvm/tools/llvm-shlib generates, and add that the the clang exports list that clang/tools/libclang contains. That would give you LLVM + libClang. If you need other Clang CAPIs you'd also need to build a mechanism for generating those export lists.

Totally possible, but not supported.
