illumos gate

Looking at recently builds, on both platforms, I've noticed that we're getting certain .debug_* sections in certain output binaries (/usr/ucb/tset is a good example).

This is confusing for a couple of reasons, firstly because Studio should be using stabs, so these are binaries to which -xdebugformat=stabs is not being passed (that is, binaries which don't use CTF, probably) and secondly that we should be stripping this stuff (and, until recently, were doing so).
