 Description   

We have some evidence that the stacktrace capture enabled in SERVER-27451 has adverse performance effects on platforms for which gperftools does not have a hand-rolled assembly backtracer, and falls back to libunwind, or glibc backtrace.

We should only enable stack capture on x86_64 and ppc.
