While we're building kernels -g (ie, makeoptions DEBUG=-g), use -O as it
provides truer debugger stack traces. For those that want to stick with
-O2 kernel builds, one should probably add -fno-optimize-sibling-calls
so that each stack frame as a frame pointer.
It is semi-promissed by the Release Engineers that when RELENG_6 is
created we go back to -O2.
