# There are three ways the Standard Library is compiled in bytecode:
# 1. During coldstart
#      - using ../boot/ocamlc which runs on ../boot/ocamlrun
# 2. During coreall (via library),
#      - using ../ocamlc which runs on ../boot/ocamlrun
# 3. During coreboot (via library-cross),
#      - using ../ocamlc which at that point runs on ../runtime/ocamlrun
# If $(USE_BOOT_OCAMLC) is non-empty, we select case 1 and use $(BOOT_OCAMLC).
# Otherwise, we use $(OCAMLRUN) ../ocamlc, with $(OCAMLRUN) being
# ../boot/ocamlrun by default, but able to overridden by library-cross to
# ../runtime/ocamlrun.
