[Patch, testsuite] Add ffat-lto-objects to gcc.target/avr/torture/builtins_error.c

[Senthil Kumar Selvaraj]

Hi,

  This patch adds -ffat-lto-objects option to an avr target testcase.

  The compiler defaults to thin LTO objects if built with linker plugin
  support, and the error expected by the testcase appears only at link
  time, if at all. Forcing fat LTO object file creation generates the
  error consistently at compile, as expected.

  Committed to trunk.

Regards
Senthil
