The default setup-hook for gcc-wrapper adds include directories with -isystem, which upsets the order -I flags are processed. This adds an alternative setup-hook that only uses -I flags. The build system's ordering of -I flags is then respected. This is important when different packages provide includes with the same name, such as building packages that depend on Qt4 and Qt5.
