Subject: [PATCH 1/3] Pass struct mem_sym into machine_apply_elf_rel()
On PowerPC64 ABIv2 we need to look at the symbol to determine
if it has a local entry point. Pass struct mem_sym into
machine_apply_elf_rel() so we can.

Subject: [PATCH 2/3] ppc64: purgatory: Handle local symbols in ELF ABIv2
The PowerPC64 ELF ABIv2 has the concept of global and local symbols
and information on this is encoded in sym->st_other. When doing a
R_PPC64_REL24 branch we want to hit the local entry point, so adjust
it as necessary.
