Comment (by kencu):

 I think the broken logic is in this cmake file `llvm-5.0.0.src/projects
 /compiler-rt/cmake/Modules/AddCompilerRT.cmake`, presumably in the install
 directory sorting. CMake is hard to decipher with so many included
 modules. Needs a debugger or something.

 I note most of the compiler_rt modules are installed as STATIC, and only a
 few are SHARED. I don't know yet if the other SHARED ones are broken too.

 Shared ones I found are:
 {{{
 clang_rt.asan
 clang_rt.lsan
 clang_rt.tsan
 clang_rt.ubsan
 clang_rt.stats
 }}}
