MC: Redirect .addrsig directives referring to private (.L) symbols to the section symbol.
This matches our behaviour for regular (i.e. relocated) references to
private symbols and therefore avoids needing to unnecessarily write
address-significant .L symbols to the object file's symbol table,
which can interfere with stack traces.
Fixes check-cfi after r339050.
