Putting the pieces together - is my understanding correct, that
clang-cl is now largely ready to cross-build ABI-compatible Windows
binaries from Linux?

Background: Mozilla is in the process of switching over to full
cross-building (https://glandium.org/blog/?p=4020). The clang-cl
compatibility page though has a few caveats still:
https://clang.llvm.org/docs/MSVCCompatibility.html.

Or is that crack-smoking?
