Comment:
@andrewrk if you try to do the regular build with the gcc-cross toolchain, it will try to run the arm64 `llvm-config` to get the link options. However, the emulator isn't setup so it can't run, and it would report the library include dir being at the host root instead of the arm64 root anyway. (`/lib` instead of `/usr/aarch64-linux-gnu/lib`) I'm sorry, I don't have a lot of experience with this, so I can't explain very well.

The cross options in zig's cmake does get around this, but I had to hack the template a bit to get it to work. See here https://github.com/jjsullivan5196/void-packages/blob/zig-cross/srcpkgs/zig/template
