It was added by Dmitry Antipov in 2012. I never use it, and didn't even
recall it until I looked at configure.ac recently.
I've not have good luck with -lto elsewhere. It can make linking slow
and it tends to expose compiler bugs. Unless someone's using it
regularly I would consider it experimental.

Yes, but if getconf is missing 'configure' is supposed to do something
reasonable anyway.
