One of the things I always build before booting is strace. With LFS
from 20190721 strace-5.2 was fine. But with 9.0-rc1 it ftbfs. I'm
recording the details here because using the git version is more
complicated than I expected (last time I needed a patch, I was able
to find one with google and apply it to the release).
The error with 5.2 was
gcc -DHAVE_CONFIG_H -I./linux/x86_64 -I./linux/x86_64 -I./linux -I./linux -I.

Note that is using my CFLAGS, those are not the problem.
Google found a similarish report from one of the travis-ci systems
running the testsuite, with a reply "Yes, there was a change in
mainline kernel headers. The issue will go away as soon as you
rebased your branch to the current master."

So, I cloned from github (gitlab is also available) and looked at
the log but couldn't pot anything that looked likely. Then I tried
to use git-archive to tar it up - total failure. The required
procedure is:
git clone
cd strace
./bootstrap
You have to be in the git tree to run bootstrap, otherwise it will
error after a while.
At that point it can be tarred up (after the previous issues I just
copied everything to a versioned directory and tarred that).
It builds, and it also runs its tests without errors (I don't
normally bother with the tests).
