qt5base: support OVERRIDE_SRCDIR

With OVERRIDE_SRCDIR we don't apply any of the qt5base patches, but the
custom specs files are needed to be able to build - So install these in the
configure step instead of having them as a patch.

-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.
