[Patch] XFAIL srec tests for avr

[Senthil Kumar Selvaraj]

Hi,

  This patch sets the status of tests in srec.exp as XFAIL for the
  avr target.

  The tests have been failing for quite a while (years IIRC).
  Turns out that the code path for srec output does not call
  elf32_avr_relocate_section - that function calls
  avr_final_link_relocate to do custom reloc handling outside of
  what's expressed in the reloc howto table. The srec code path
  calls bfd_perfom_relocation instead, and that function, which only
  looks at howto table information, generates junk values, causing
  the tests to fail.

  Just calling that function from
  elf32_avr_get_relocated_section_contents didn't work - there's some
  state set up through elf32_avr_link_hash_table_create (which
  implements bfd_elf32_bfd_link_hash_table_create hook), and that's
  missing in the srec generation code path. I gave up at this point :)

  An easy and well-known workaround exists - linking to ELF and then
  using objcopy to convert to srec.

  If ok, could someone commit please? I don't have commit access. The
  formatting looks weird - I went by neighboring code's formatting.

Regards
Senthil
