commit a95c4ad24cf83b2b0273fee73162bf476cebec8f

Author: Mark Wielaard <mjw@redhat.com>

Date:   Fri Jul 4 14:30:48 2014 +0200

    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.
