While this sounds reasonable to me, it appears to add quite some effort. I guess we grow our own writer that can emit in-memory ELF objects in some specific format, but there's a load of details that would need consideration sooner or later: recalculating offsets, compressed sections, etc. Doing it right would probably mean something like `llvm-objcopy --only-keep-debug`. The implementation of it is buried with the tool implementation currently, so I can hardly "just use" it: https://reviews.llvm.org/rG5ad0103d8a04cb066dfae4fc20b0dfcd9413f4d4

What do you think?

(I will try a hack in the next days to see whether it's viable at all, but I'd would keep hopes low that we get there anytime soon.)
