Looks like this has not be settled. Will create a ticket, since this seems to have been forgotten. I tend to agree with Ken, but we are so close to 8.2 that breaking compatibility with 8.1 might not matter so much.

Since we claim to support older versions of
LFS (and 2.27 is a very recent change) I think we'd better use the
upstream patch - builds with autoreconf -fiv && intoolize -f.
This was only suppsoed to be a dry run to find the bugs in my own
buildscript changes. Aren't toolchain changes a pleasure.
I thought I fixed that, but upon research, it never made it into the book.
