If you start off with "___gnu_lto_", there is code in simple_object_elf.c to
handle the extra '_', and now in binutils too.  Skipping just one '_' will
leave you with a symbol that matches "__gnu_lto_", and will trigger the gold
warning.  Skipping two chars will give you "_gnu_lto_" which ought to be fine.

Of course on x86_64, you'll start off with "__gnu_lto_", skip two chars to give
"gnu_lto_", which also ought to be fine.  Even if it matches some user symbol.
