This violates ELF standard for the application callers of dwfl_module_getsym:
In each symbol table, all symbols with STB_LOCAL binding precede the
weak and global symbols.
As long as the dwfl_module_getsym interface represents a single symbol table
which seems so according to its description:
Fetch one entry from the module's symbol table.
