| 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. |
