how about the SWR maintainers provide a "golden" fallback file, that is
pre-generated and known good for all supported LLVM (right now I would guess
that to be 3.9 and 4.0) versions? That file is always shipped in the tarball.

During build there's a rule, that checks if $generator is there. If not, the
fallback file is copied to the correct name, otherwise the regular generation
takes place.

Cheers,
Kai
