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.
