Thanks, but I'll leave that for somebody else to try. It certainly sounds as if it ought to work, but I've now got it to a stage where it builds LFS conventionally so I don't have any need to build the binaries on a slower system. Too much else to get on with (firefox, gimp-2.10, TeXlive-2018) plus whatever else turns up. I'll note that using those options probably allows a build on an intel (or on an AMD and then transfer to an intel), so it is an interesting suggestion. ĸen -- Before the universe began, there was a sound.
