#     kbuild: rebuild multi-object modules when objtool is updated
#     
#     When CONFIG_LTO_CLANG or CONFIG_X86_KERNEL_IBT is enabled, objtool for
#     multi-object modules is postponed until the objects are linked together.
#     
#     Make sure to re-run objtool and re-link multi-object modules when
#     objtool is updated.
