Comment:

 Replying to [comment:2 rwbarton]:
 > Oh, hmm, I actually looked at the code and we do already inspect the
 error string from `dlopen` and try to parse a linker script. The problem
 is that we don't support `INPUT(-llibrary)`. I guess we can transform the
 name to `liblibrary.so` in that case?

 I think that's what's needed. I don't run Arch Linux right now. Maybe I'll
 have some time to install it in a VM and try out this approach.

 When I fixed #2615, the hardest part was generating a test to prove it
 worked. I envision the same difficulty here.

 > I still would like to avoid incurring dependencies on `.so`s that are
 really linker scripts, if possible...

 I don't see any way to avoid this unless we find a way to call `ld` as a
 helper. Doing this would be way beyond my level of understanding.
