Recently @avsm mentioned a matrix of things to do related to cross compilation and seems like there is some progress happening in this like #9817
Is that matrix public? I want to look on this but trying to avoid duplicated work, mostly I want a cross compiler using something like clang
--target which seems relatively simple after #9817, also the cross word compilation(64bits to 32bits).
@dra27 was also mentioned, so pinging to get some reach
