Okay. Posting for the sad guy who lands here having the same problem and got no help.
I suspect nobody at google has tried building for android from a mac host before. Everything above was required, but the biggest culprit was those "Release+Asserts/include/c++" headers which infected the arm build and conflicted with my final linker step. I basically had to hack it to not use those headers (so it defaulted to the ones from my ndk toolchain) but ONLY for the arm64 build. The host build still required those to be in place. It took alot of messing around, but doing that that finally got it to link.
