#
#     For each archive mentioned on the command line after the
#     --whole-archive option, include every object file in the archive in
#     the link, rather than searching the archive for the required object
#     files.
#
# In our case, we find the plugins thanks to special sections in the
# binary that are filled by plugin objects. If the linker discards those
# symbols because the CLI does not use them directly, the CLI reports
# no plugins found (plugins are effectively not embedded).
