I'm not sure exactly what you want, but we do already have a form of this.
If you use the low-level llvm-link program (or gccld --link-as-library),
it will take all of the .bc files specified, link them together into a
_single_ bytecode file, and write that out (gccld performs IPO on the
result).

Is this what you mean?  Is there any reason to keep the .bc files distinct
like a ".a" file, or is it ok for your purposes to link them together into
a single unit, like a ".so" file?
