            Bug ID: 47163
           Summary: compiler-rt cannot be compiled with llvm on arch
                    linux: realpath redefinition
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: tsan
          Assignee: unassignedbugs at nondot.org

am trying to create a swift-lang package for arch linux, with a continuous
build here: https://github.com/soloturn/swift-aur/actions 

funny is that on arch linux which first has newest packages, and second, dev
packages do not exist, there is just one package including the developer
version in many cases.

compiler-rt can be built with g++, but using clang++ fails

$ export CC=clang
$ export CC=clang
$ makepkg -s

and it really gives the same error when compiling swift.
