Initial support for the ELFv2 ABI
Provide an experimental option to compile using ELFv2 ABI even on big endian builds. ELFv2 + BE is not officially supported by the toolchain, but it works quite well. It may be useful as a small step toward a little-endian build. This saves about 200kB of text/data.
