If it is set, then that target is invoked for each architecture rather than the default action of building world and kernels for each architecture. - Add a 'make toolchains' wrapper which uses UNIVERSE_TARGET to build toolchains for all architectures. - Document JFLAG, MAKE_JUST_KERNELS, and MAKE_JUST_WORLDS variables for 'make universe'.
