arch: add OpenRISC architecture support
Add support for OpenRISC. See here for more details about OpenRISC http://openrisc.io. All buildroot included upstream binutils versions are supported. Gcc support is not upstream, to be able to enable musl C library support later, we use the branch with musl support. At the moment it is possible to build a musl based toolchain, but bootup in Qemu fails. Gdb is only working to debug bare-metal code, there is no support for gdbserver/gdb on Linux, yet.
