We tried that early on in modularization for all the libraries and apps,
which is why they have strangely worded configure messages such as:

checking for ICO... yes

when you're building ico (it should really be "checking for the packages that
ICO needs"), due to commits such as:
http://cgit.freedesktop.org/xorg/app/ico/commit/?id=5c31a07dbcb735445951f7f7cae8579ee16262d5

Unfortunately, it doesn't seem to have been consistently applied or kept up.
