Using icecream obtained via Homebrew on macOS, I tried to create a toolchain for from the clang 8.0 pre-built binaries from the clang website (I also tried 7.0, but had the same problem). I ran:
wget http://releases.llvm.org/8.0.0/clang+llvm-8.0.0-x86_64-apple-darwin.tar.xz
tar xvf clang+llvm-8.0.0-x86_64-apple-darwin.tar.xz
/usr/local/Cellar/icecream/1.2/libexec/icecc/icecc-create-env --clang ./clang+llvm-8.0.0-x86_64-apple-darwin/bin/clang /usr/local/Cellar/icecream/1.2/libexec/icecc/compilerwrapper
This does a lot of work and almost completes successfully, but just before the end this happens:
<snip>

Couldn't create archive
It seems that the path to clang+llvm-8.0.0-x86_64-apple-darwin/bin/clang specified to icecc-create-env needs to be an absolute path to avoid this error.
Presumably this gotcha could be eliminated if icecc-create-env would fix up a relative path before using it internally. (Or by fixing the code that ends up resolving relative paths against the wrong directory, but I guess that may be less trivial.)
I originally filed this issue with Homebrew but apparently they don't customize icecream, so presumably it's an issue with the vanilla icecc-create-env script.
