eugghh. Another example of outside-the-book documents falling behind
(or being used for more than was intended - building 2.6 kernels with
gcc-2.95.3 is probably fine for most things except nptl).

The 'pure lfs' method started out by running all of the tests.
Eventually the non-toolchain tests in chapter 5 were discouraged because
of unexplained problems on certain hosts / distros (tests failed in
chapter 5, but chapter 6 was ok). Anybody who cares about the book
should prolly be running the chapter 5 tests, at least to look for new
failures. But, if the book suggests you should skip the toolchain tests
in chapter 5 (I say 'if' because I'm not following CVS at the moment)
then the book is _wrong_.

Agreed. As you've shown us, "ignore the tests if you used 2.95.3" isn't
always a viable answer.
das eine Mal als Tragödie, das andere Mal als Farce
