Fat LTO is just too slow. I suspect with that kind of performance

It's not too hard in my experience. I did it in a few cases for gcc.
The gcc maintainers unfortunately didn't want to integrate the
wrapper scripts to make it easy, but they can be always downloaded
separately and I assume distributions will eventually ship
them anyways.
