Build OpenJDK 8 on MacOS Mojave (10.14.3)

[Simon Tooke]

I have successfully done this (with some very important caveats that
make it useful only for hacking the JDK at this point).

Please let me know if you have any comments or corrections to my rough
guide:

I'll write a shell script at some point, and clean up the patches into a
proper PR.

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.
