Add ppc64le ELFv2 abi support to backends and elflint.
The big endian vs little endian changes are already handled by detecting
the EI_DATA data encoding. And the function descriptors are already not
used when we see there is no .opd section. This change adds new checks
for st_other bits, new relocations and recognizes DT_PPC64_OPT.
