This is what I did - it's really just a set of patches that are applied
within a Debian package building framework:

https://github.com/david-boddie-met-no/qt4-headless/tree/4.8-qpa

The configuration removes as much as possible from the build, so you
wouldn't want to try and use it to build a virtual GUI framework.
The use case for this is a library that renders images for a server.

There are various patches in there to fix some Qt headers - it seems
that some feature-sensitive code is not properly wrapped in #ifdef
checks. Are the cut-down Qt builds still tested these days?
