[Buildroot] [PATCH 0/6] Build a Nios-II internal toolchain

[Ezequiel Garcia]

Now that Linux, GCC, glibc, and binutils have gained a Nios-II
port we can build an internal toolchain.

This series mostly makes sure only the right versions of the components
are chosen when building a toolchain. The last patch merely enables
the internal toolchain.

I would like to prepare a defconfig, along with support for some real life
board, but unfortunately I'm unable to do so.

First, all the publicly available design examples for the boards I have
are outdated and won't work with mainline kernel (unless we apply nasty
patches).

Second, when working on this, the board I was using died and I'm not sure
when I'll be able to replace it.

Still, before the board died, I managed to build a toolchain, and boot
U-Boot, Linux (a patched v3.19) and get to userspace. Maybe someone
can give this a shot and report how it goes.

Or maybe we can just merge it :)
