[OpenRISC] New Install on Ubuntu 14.10

[Ouabache Designworks]

So I am now trying the install from here

https://github.com/juliusbaxter/mor1kx-dev-env/wiki/OpenRISC-tool-chain-installation-guide


using these repos:


git clone git://github.com/openrisc/or1k-src.git
git clone git://github.com/openrisc/or1k-gcc.git


And it errors out with this:

This is due to that your gcc version is producing a warning that is
then threated as an error.
It's fixed in upstream binutils, so you can either use that, or just
configure with --disable-werror

The fix for the issue seems to be this:

https://sourceware.org/ml/binutils/2014-01/msg00334.html

I'm not sure why people are drawn to that set of instructions to build the
tool chain lately, but either way I've added the missing --disable-werror
to them (I presume it's when we go to do the newlib-enabled or1k-src
configure).

Cheers
