Naming conflicts when building v8_monolith

[Jeroen Ooms]

I am building a static monolith of v8 14.6 with the following config:

    gn_args = {
      is_debug:                     false,
      is_component_build:           false,
      v8_use_external_startup_data: false,
      v8_enable_fuzztest:           false,
      v8_enable_i18n_support:       false,
      clang_use_chrome_plugins:     false,
      treat_warnings_as_errors:     false,
      use_custom_libcxx:            false,
      enable_rust:                  false,
      use_sysroot:                  false,
      v8_enable_temporal_support:   false,
      v8_monolithic:                true,
      v8_static_library:            true,
      v8_enable_partition_alloc:    false,
    }

The build succeeds but in the end there are some worrysome linker warnings. Are these ignorable? In some cases they seem to be completely different sources, e.g. time.o ?
