In general, if the codebase of a certain project is compilable by
Clang/LLVM, this should be possible, but the devil is in the details (for
example - how is the standard library going to get compiled into that .bc
file?)

I suggest you take a look at the "NaCl ports" project (
https://code.google.com/p/naclports/). It has ready-made makefiles to
compile a bunch of well known open source projects using the PNaCl
toolchain, which is based on LLVM. Each file is compiled to IR and the LLVM
linker is used to link them all together. This is a full solution, handling
the standard libraries, and so on.
