1090+ relocatable output file) adjusting the reloc addend as
1091+ necessary.

1101+ The global hash table entry for the global symbols can be found
1102+ via elf_sym_hashes (input_bfd).
1103+
1104+ When generating relocatable output, this function must handle
1105+ STB_LOCAL/STT_SECTION symbols specially. The output symbol is
1106+ going to be the section symbol corresponding to the output
