Commit: MSP430: Add -mhwmult=none to build command line

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix the build of newlib for the
  MSP430 target.  The problem here is that availability of hardware
  multiply support in the target is not known at build time, and so it
  cannot be relied upon.  Instead a software multiply function is used.
  The will make the library slightly slower, but also work properly for
  all MSP430 MCU types.

Cheers
  Nick
