[PATCH] D61563: [ELF] Error on relocations to local undefined symbols

I think compilers don't produce local undefined symbol. However, users can write such invalid assembly files (see our amdgpu-relocs.s test)

Also, the "undefined" semantic can be brought up by a symbol defined in a discarded section (COMDAT or SHF_EXCLUDE). The latest report can be found at https://bugs.llvm.org/show_bug.cgi?id=41693  Such (relocations to STT_SECTION symbols whose sections are discarded) errors occur occasionally.
