backends: Add PPC64 machine_flag_check.
To distinguish between the current PPC64 ELF ABI and the revised
ELFv2 ABI that will not use function descriptors binutils started
to emit the version (currently 1) in the ehdr e_flags. Recognize
all valid versions (0, 1 or 2) in elflint by adding the hook
ppc64_machine_flag_check.
