QT_COMPONENTS can now be depended on at runtime or buildtime only by
specifiying them as <component>_build or <component>_run, respectively.
Specifying <component> without any suffix will depend on the component
at both build- and runtime just like before.
- Convert Qt core ports to use the new dependency switches.
- Add a patch to corelib to fix Qt4 on ARM, submitted by:
