Build OpenJDK 8 on MacOS Mojave (10.14.3)

I have (with a couple of small changes) built 8u on the latest macOS +
XCode.  The laptop with that build is at home right now, so I cant
forward a patch.  It was mostly fixing clang debug file generation and
updating Xcode version checking.

My build runs fine but crashes on shutdown in
PerfDataManager::destroy().  Interestingly, it was an issue for some
people building JDK 9, too [1]; I suspect it won't be too hard to track
down, but since it's a weekend project I haven't got to it yet.

I'll poke at it this evening.

However, I’m thinking, since OpenJDK 8 is not completely legacy yet, at least a developer build should be possible on a current operating system. I would accept having to install the oldest running Xcode compiler for sure, but not at all being able to build on a recent MacOS is not good.
