[PATCH] [MSP430] Pass -mcode/data-region to the linker and assembler

[Jozef Lawrynowicz]

The changes made in a series of binutils patches
(https://sourceware.org/ml/binutils/2017-08/msg00274.html)
to ld and gas require the -mcode/data-region options to be propagated
from gcc.

The attached patch adds that functionality.

If the patch is acceptable, I would appreciate if someone could commit
it for me, as I do not have write access.

Thanks,
Jozef
