When building for a target architecture that go does not support, the
installation fails with:
$ make host-go
[...]
ln -sf ../lib/go/bin/go /home/nyma7486/dev/work/5GCroCo/O/pouet/per-package/host-go/host/bin/
ln: failed to create symbolic link '/home/nyma7486/dev/work/5GCroCo/O/pouet/per-package/host-go/host/bin/': No such file or directory
Indeed, the HOST_DIR/bin is not guaranteed to exist when we install a
host package, so it needs to be explicitly created before we can create
entries in there.
