[New-bugs-announce] [issue24318] Make profile-opt the default Make target?

New submission from Skip Montanaro:

In a discussion on python-ideas about some computed goto stuff, Greg Smith brought up compilation with "profile-opt", which I'd never heard of. I asked Greg about it and he enlightened me. Looking around, I saw no mention of this make target except in the Makefile itself, and a small what's new note for Python 2.6. I was only looking on the 2.7 branch, but aside from a bug fix mention in Misc/NEWS for Python 3.4, it doesn't seem to feature more prominently there.

It would seem to be stable. Should it perhaps be the default when available (presuming the proper configure tests can be written)? Alternatively, it could be featured more prominently in the build instructions. I've attached a simple patch to README for that.
