That would be host_os.  Consider this example: a system running on cpu
FOO cross-compiles grub (i.e. stuff like grub-probe or grub-mkimage)
so that it will run on cpu BAR.  However, grub-mkimage should generate
images for cpu BAZ (accordingly, the modules are built for BAZ too).

This means build_cpu=FOO host_cpu=BAR target_cpu=BAZ.

host_os, then, is the OS that runs on BAR.  It isn't necessarily related
to BAZ.
