Comment 2 for bug 13737

I'm pretty sure mkfontscale belongs in xutils, but if it doesn't, mkfontdir
should really be punted to xbase-clients. The difference between the two is
that xutils is just random crap that doesn't require client-side X libraries
(you can do it without libXau/libX11/et al installed), and xbase-clients are
base X clients (i.e. they require X client-side libs). Having xutils depend on
xbase-clients would be pretty counterproductive, thus. I'll work out the proper
fix for this one tonight and roll it into my post-preview upload.
