Refactoring in 4986cb14 introduced an unintentional behavior change:
private symbols are now findable in symbol table with lookup by
signature.
Unfortunately, this is not correct - private symbol signature might not
be unique (or at least was sometimes not unique in older compiler
versions), which leads to crashes on deserializing corresponding klib.
This commit restores old behavior.
