I think it is dangerous to just match the start of the symbol name here -
this may in the future well lead to ignoring symbols we shouldn't be
ignoring.
Also I would think the added comment ought to say "Ignore LTO symbols."
Otherwise its sort of contradicting the purpose of the case being handled
here.
