perf_counter: tools: Makefile tweaks for 64-bit powerpc

On 64-bit powerpc, perf needs to be built as a 64-bit executable.
This arranges to add the -m64 flag to CFLAGS if we are running on
a 64-bit machine, indicated by the result of uname -m ending in "64".
This means that we'll use -m64 on x86_64 machines as well.
