[PATCH] [MSP430] Fix open syscall not working in simulator

[Nick Clifton]

Hi Jozef,

> The syscall "open" does not execute correctly in the msp430 simulator.

> functions with arguments that fit in registers.

Approved and applied.

Note - for future reference - the simulator is part of GDB not the
binutils, so you need to submit patches to gdb@sourceware.org...

Cheers
