This problem shows up with parallel builds only; it results in somewhat cryptic error messages like

$ JOBS=-j6 MAKEALL netstar Configuring for netstar board... arm-linux-ld: cannot find -lgeneric make[1]: *** [eeprom.srec] Error 1

A few boards (like netstar and voiceblue) need some libraries for building; however, the board Makefile does not contain any such dependencies which may cause problems with parallel builds. Adding such dependencies is difficult as we would also have to provide build rules, which already exist in the respective library Makefiles.

To solve this, we make sure that all libraries get built before the board code.
