xcodebuild necessary on Mac?

No, the SDKs are in the app bundles. The frameworks in /System used to have headers installed with the developer tools, but Apple is moving away from that. The frameworks themselves are managed by the OS install/update. Maybe the command line tools still install headers there.

run this:
$ find /Library/Developer/CommandLineTools -name '*.sdk'

I'm curious to see what's there... If the SDKs are there then we should be able to support building OpenJDK with just the command line tools installed.

That won't be the case for closed source though, you still need the full Xcode app installed.
