MSP430: Fix problem initialising .upper.bss section

[Nick Clifton]

Hi Guys,

  I am checking in the patch below to fix a problem initialising the
  MSP430's .upper.bss section.  I forgot to include a definition of the
  __high_bssisze symbol in the linker script, and without the code in
  crt0.S will not fill the section with zero bytes.

Cheers
  Nick
