GCC build with for OR1K

[Hesham ALMatary]

Hi Alexander,


The current GCC upstream support for OpenRISC is obsolete, it dates
back to the old or32 port which is now replaced by or1k tools.
OpenRISC folks are working on pushing their latest GCC or1k work
upstream but they currently have some issues with FSF papers.

For RTEMS or1k port to work, we had to generate our own patch between
or32 and the updated (non-upstreamed yet) or1k GCC work. This patch is
against GCC 4.8.3 release. You can try to build GCC from their repo
here [1] but I think it's not syncrohnized with GCC 5.0.0 (yet).

Thanks,
Hesham
