RFA: Testsuite: Add exceptions for MSP430

[Nick Clifton]

Hi Guys,

  The new MSP430 target has a few limitations which show up as
  unexpected failures in the GCC testsuite.  I would like to apply the
  patch below to update target-supports.exp with this information.
  Applying the patch results in a drop of 133 unexpected failures (per
  multilib).

  OK to apply ?

Cheers
  Nick
