ARM crt0.o: Add NULL to end of argv[]

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a small bug in the ARM crt0.o
  file for newlib.  The code was creating an argv[] array from the
  command line, but it was not terminating the array with a NULL
  pointer.  This is required by the ISO C specification, and this
  patch fixes the problem.

Cheers
        Nick
