Commit: Expect extract symbol test to fail for MIPS

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  I have decided not to pursue my idea for "fixing" the
  --extract-symbols operation of objcopy so that it preserves target
  specific sections.  The operation is only intended to be used for
  generating VxWorks symbol files, so creating invalid MIPS ELF binaries
  should not matter.

  Instead I am applying the patch below (mainline and 2.26 branch) to
  mark the extract symbols test as an expected failure for the MIPS
  target.

Cheers
  Nick
