cmd/9l: support internal linking
This implements the ELF relocations and dynamic linking tables
necessary to support internal linking on ppc64. It also marks ppc64le
ELF files as ABI v2; failing to do this doesn't seem to confuse the
loader, but it does confuse libbfd (and hence gdb, objdump, etc).
