#     kbuild: reuse $(cmd_objtool) for cmd_cc_lto_link_modules
#     
#     For CONFIG_LTO_CLANG=y, the objtool processing is not possible at the
#     compilation, hence postponed by the link time.
#     
#     Reuse $(cmd_objtool) for CONFIG_LTO_CLANG=y by defining objtool-enabled
#     properly.
#     
#     For CONFIG_LTO_CLANG=y:
#     
#       objtool-enabled is off for %.o compilation
#       objtool-enabled is on  for %.lto link
#     
#     For CONFIG_LTO_CLANG=n:
#     
#       objtool-enabled is on for %.o compilation
#           (but, it depends on OBJECT_FILE_NON_STANDARD)
#     
#     Set part-of-module := y for %.lto.o to avoid repeating --module.
