Make the use of -fdata-sections and --gc-sections more generic in Qt
Add qmake feature and configure option, which optimze the size of static exectuable. Use for static build. Enabled via configure --gc-binaries, or CONFIG += gc-binaries in 3rd party projects. Change-Id: I3c25b02caaef6a4afc6019afc9c67122dd11696d Reviewed-by: Oswald Buddenhagen <>
