Simplify our custom qmake.conf:
- Include linux_device_{pre,post}.conf to inherit common device
configuration.
- Do not add $(STAGING_DIR)/usr/include to include path. It is
redundant.
In additon to the simplification of code, this change is a preparation
to solve problems occurring when QMAKE_CXX is prepended with ccache path.
Upstream patch is needed by configure to parse device options correctly.
Another upstream patch is needed to remove ARM specific parts from
linux_device_post.conf.
