Only use ccache prefix in QMAKE_CC and QMAKE_CXX since the build system is broken when QMAKE_AR contains a space character. Remove the upstreamed uClibc patch. Signed-off-by: Fatih Aşıcı <fatih.asici@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

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.
