This patch adds a support for OUTPUT_FORMAT linker script directive. Since I'm not 100% confident with BFD names you can use in the directive for all architectures, I added only a few in this patch. We can add other names for other archtiectures later. We still do not support triple-style OUTPUT_FORMAT directive, namely, OUTPUT_FORMAT(bfdname, big, little). If you pass -EL (little endian) or -EB (big endian) to the linker, GNU linkers pick up big or little as a BFD name, correspondingly, so that you can use a single linker script for bi-endian processor. I'm not sure if we really need to support that, so I'll leave it alone for now. Note that -m takes precedence over OUTPUT_FORAMT, but we always parse a BFD name given to OUTPUT_FORMAT for error checking. You cannot write an invalid name in the OUTPUT_FORMAT directive.
