Which linker do you use, and what's the value of HAVE_LTO_PLUGIN in
gcc/auto-host.h? Could you check the gcc/config.log snippet for the
linker plugin support test.
If, as I assume, you're using the Darwin linker, HAVE_LTO_PLUGIN should
be 0 and you should get the following error for the linker_plugin test:
gcc: error: -fuse-linker-plugin is not supported in this configuration
