Provide support for userland binaries using the new ELFv2 ABI. This is a
new, simplified, ELF ABI that avoids some of the stranger aspects of the
existing 64-bit PowerPC ABI (function descriptors, in particular). Actually
generating such executables requires a new version of binutils and a newer
compiler (either GCC or clang) than GCC 4.2.1.
