powerpc/64s: allow for clang's objdump differences
Clang's objdump emits slightly different output from GNU's objdump, causing a list of warnings to be emitted during relocatable builds. E.g., clang's objdump emits this: c000000000000004: 2c 00 00 48 b 0xc000000000000030 ... c000000000005c6c: 10 00 82 40 bf 2, 0xc000000000005c7c while GNU objdump emits: c000000000000004: 2c 00 00 48 b c000000000000030 <__start+0x30> ... c000000000005c6c: 10 00 82 40 bne c000000000005c7c <masked_interrupt+0x3c> Adjust llvm-objdump's output to remove the extraneous '0x' and convert 'bf' and 'bt' to 'bne' and 'beq' resp. to more closely match GNU objdump's output. Note that clang's objdump doesn't yet output the relocation symbols on PPC.
