Commit: MSP430: Built libgcc with hardware multiply disabled


Hi Guys,

  I am applying the patch below (to mainline and the 4.9 branch) to fix
  a problem when building libgcc for the MSP430.  The problem was that
  the software multiply functions were being renamed to the hardware
  multiply equivalents, and libgcc was using the hardware multiply
  feature even when it was not clear that it would be supported by the
  target MCU.  The fix is just to disable the use of hardware multiplies
  inside libgcc.

Cheers
  Nick
