This discussion came up in conda-forge/clangdev-feedstock#246 recently:

@h-vetinari: Do I understand you correctly that you're proposing to introduce clang_linux-64?

@xhochy: Yes, but don't expect it to happen anytime soon.

@isuruf: I tried that recently and realized that some of the symlinks are in wrong packages. See my WIP PR conda-forge/ctng-compilers-feedstock#112

That PR has since been merged, so we can use this issue to figure out next steps.

PS. Speaking of symlinks, this issue is also quite closely related to #118.
