In the other filesystems, we do not necessarily select
BR2_PACKAGE_HOST_<utilities to build the filesystem>, and therefore we
keep the <pkg>_DEPENDENCIES that contains host-<utilities to build the
filesystem>.

I don't have a very strong opinion on which solution we should use, but
I am sure that we want things to be consistent across the different
filesystems. So for the time being:

This is not necessary.

And this should be preserved.

Unless of course we decide to change our strategy.
