Fortuinately this will be availabel soon :) I wanted to create a simple build target or similar for arm64 that mimics the s390 use of arm64 shared code but compiles using an arm64 toolchain to reduce friction for esp non-maintainers. I have some ideas. They may work. Let's talk at plumbers about that. Steffen
