Enable PIEs for m68k-linux

[Nick Clifton]

Hi Joseph, Hi Roman,

>> This patch makes ld generate the linker script required to build PIEs

> Could we also set COMMONPAGESIZE (which would enable the relro option) to 
> bring m68k into sync with other elf targets?
> I can confirm that this patch works on real m68k hardware.

I have applied both changes along with this changelog entry.

Cheers
