[issue25702] Link Time Optimizations support for GCC and CLANG

[Antoine Pitrou]

Antoine Pitrou added the comment:

Any non-bugfix introduction can introduce instability. That has always been our position with respect to adding features to bugfix branches. I don't see how adding a LTO option this late in the 2.7 release cycle can be considered important enough to break that rule.

Let me add that downstream distributors already customize compilation options (Ubuntu's Python is compiled with both PGO and LTO enabled, AFAIR), so this change may only really affect the tiny subset of non-Windows users that compile Python themselves.

But well, perhaps Python development has become boring to the point of deliberately introducing uncertainty and risk to make things a bit more fun? ;-)
