* Makefile (STDLIB_SRCS, STDLIB_TLOS, STDLIB_TLOS2): New
variables.
(COMPILE_TL): New recipe macro.
(%.tlo, %.tlo2): New pattern rules.
(all): Depend on new stage1 and stage2 targets.
(stage1, stage2): New phony targets.
(clean): Add clean-tlo dependency.
(clean-tlo): New phony target.
(install): Install .tlo files also.
