[ARC] Fixes related to reordering of .got and .got.plt

Browse Source 
- Correctly solved relocations on the .got header.
- This bug arrised from enabling RELRO (-z combreloc).
  Because the .got and .got.plt sections were split in new linker
  scripts the header is no longer part of sgotplt contents.
  Changed the patch to sgot contents instead.
- Latest fix to .got header relocs.
