I think that's what you get when using my approach:

doOpenGLDesktopTest() {
    if [ "$QT_QPA_DEFAULT_PLATFORM" = "cocoa" ] || \
       [ "$QT_QPA_DEFAULT_PLATFORM" = "" -a "$XPLATFORM_MAC" = "yes" ]; then
        # QT_QPA_DEFAULT_PLATFORM is either empty or set by the user,
        # so we have to check both manually and automatically selected cocoa.
        # It qpa=cocoa, we do NOT want to use pkg-config to find the OpenGL
        # libraries because it's too likely to find OpenGL libraries that are
        # not the system frameworks appropriate for cocoa mode.
        compileTest unix/opengldesktop "OpenGL"
        compileTestWithPkgConfig gl unix/opengldesktop "OpenGL" OPENGL

Well, yes, but as long as you provide the appropriate SDK argument, -framework 
OpenGL -framework AGL will still link the correct framework, no?
