- Add a Buildroot 'device' to ease cross-compilation
- Qt5 has a mechanism to support "device" profiles, so that people can
- specify the compiler, compiler flags and so on for a specific device.
- We leverage this mechanism in the Buildroot packaging of qt5 to
- simplify cross-compilation: we have our own "device" definition, which
- allows us to easily pass the cross-compiler paths and flags from our
- qt5.mk.
