QToolbar on OSX static builds

When compiling Qt 5.1 with -static or trying to get the frameworks inside the app bundle the toolbar buttons look different (see screenshot).

The first window is compiled using the binary Qt5 installer from the website (with shared frameworks) and the second window is what I get when I copy the Qt frameworks to the bundle and fix the library paths using install_name_tool or link the app against static Qt libraries I compiled myself from the 5.1 source.
