I have looked into the issue and shared my findings [1]. If the bug is 
not as easy to resolve as I currently think it is, I also offered to 
upload a cmake-3 legacy package as a temporary band-aid, but I have not 
heard back from the LLVM maintainers yet.


Cheers

The root cause is the support for WebAssembly targets. WebAssembly does 
not support shared libraries; older CMake releases just issued a warning 
and built static libraries instead, but this is no longer the case. LLVM 
upstream said the shared library build for runtime libs is not the 
default, so this must have been enabled somewhere in the Debian 
packaging. I could not figure out where, but I would assume the actual 
maintainers can.
