I don't know much about the finer points of cygports, but I'll comment on a couple of things

That sucks, and should really be fixed to only have one case of that directory. > Bootstrapping llvm worked, but the tests can not be run due to missing > googletest. Huh. The gtest stuff is vendored in the third-party tar, and is built and installed as libllvm-gtest*.a. I didn't personally try to run the tests for llvm itself, but the tests for clang and lld (in playground repo lld branch) ran fine. I don't know if any of the subsequent shuffling of test options since my last commit changed anything there though, I haven't tried since my last commit.
