Subject: [PATCH] openrisc: Support both old (or32) and new (or1k) toolchain

The output file format for openrisc has changed from "elf32-or32"
to "elf32-or1k" when using the or1k instead of the older or32 toochain.
Select the correct output format automatically to be able to compile
the kernel with both toolchain variants.
