Commit: MN10300: Generate .got entries for GOT based relocs

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a problem with the MN10300 linker
  - it was not correctly allocating space in the .got section for GOT
  based relocs.  This was because the mn10300_elf_check_relocs()
  function was not being called, which in turn was caused by the loaded
  object files being given an object_id of GENERIC_ELF_DATA instead of
  MN10300_ELF_DATA.

	(bfd_elf32_mkobject): Define.
