Hmmm, tricky question... I guess adding --enable-hopengl to the configure command line and re-running "make all" will work, but I'm not 100% sure. OTOH, adding "SplitObjs=NO" to your build options will (or at least should) result in a recompilation of all libraries, so doing a "make clean" in fptools/libraries in advance would be safer.
