I really don't see how it can be made to work in a generic wait without
requiring that all sub-arches use the same version as the main arch and
without requiring that the main arch be installed (if we were a binary
distro, we could do a common package and a bunch of sub-packages, but
now we can't).

In theory, headers in /usr/include should be arch independant. You if
you at glib, it installs its arch dependant header in /usr/lib
