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.
