I think, provided you run the package tests on GCC, Binutils and GLIBC,
and get the expected results that you will learn if you get away with it
or not. The next question is: "was it worth it?" Many have tried
optimisations only to find they make the system slower or the binaries
larger or some such.
If you want excitment, build the version in cvs HEAD (once known as
Bleeding-Edge LFS). It's the latest kernel, the latest compiler, a
risky late date glibc from cvs... and then you can help us validate the
instructions too. (subscribe to lfs.hackers mailing list first though).
