PATCH: Fix linker cross ref test for MeP

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a problem with the linker's
  cross reference tests when being run for the MeP target.  The
  problem was that the compiled test source code used the MeP's small
  data area which requires that a special symbol be provided by the
  linker script.  Since the test scripts do not provide this symbol,
  the test case failed to link properly.

  The fix is to add the MeP specific compile time option to suppress
  the use of the small data area.

  Tested by running the linker testsuite for the MeP toolchain.

Cheers
  Nick
