procps - is that a build tool?
bison, flex, gperf - common build tools, default build env packages
ruby - default package in build environment
cmake - installed by build-package.sh if necessary
Neither of these target packages are usable when cross-compiling and thus
shouldn't be specified as build time dependency.
Sampling profiler and WebKit 2 have to be disabled
Current issues (tested with the QtTestBrowser):
- Video playback not working
- No OpenGL, no WebGL (expected)
What's working: seemingly everything else
