Hi successfully built the entire chapter 5, then start of chapter 6
(because then I deviate), with the following flags for *all* software:
CFLAGS="-O3 -pipe -march=i686 -mtune=i686"
thus binutils and glibc are built with those flags. I verified in
generated logs, and just some parts weren't built with them:
libiberty, some stages of gcc, because configure override the flags.
My host machine has an i486-linux-gnu toolchain, and is reported as an
i686 GNU/Linux (uname -m and uname -o).
Hope this help
