mkfontscale on the host is required to build xfonts-encoding for the

We also fix the dependencies. xlib_libX11 is not needed to compile
xapp_mkfontscale. However, xproto_xproto is needed.

quite work yet for me, but this clearly is a huge project and not having it
quite work on the first pass is hardly unexpected. We definately want this
stuff in buildroot.
