I'm not sure what PREFER_STATIC_LIB has to do with you original problem.

As to creating static binaries when PREFER_STATIC_LIB is disabled, according 
to package/Makefile.in --enable-static is always present in 
$(SHARED_STATIC_LIBS_OPTS). Only when PREFER_STATIC_LIB is enabled 
--disable-shared is also added. In short, you can always build static 
binaries; but enabling PREFER_STATIC_LIB prevents shared binaries building.
