i dont own aarch64 hardware so i am probably not the best to comment
but one could in principle install make and needed posix tools
or one can run make on the x86 host and use --target-exec and
execute with it some script / ssh to trigger execution on the aarch64
hw. This is tricky as one also runs cross build on the host but the
build files must be on the target when they get executed
