Just another data point for the record.

Here, a senior toolchain person confirms how sysroot is meant to be used
(read the whole bug report for context):

http://lists.gnu.org/archive/html/bug-binutils/2007-08/msg00110.html

I quote:

 "You should use --prefix=/usr and install it with install_root=${sysroot}.
  The whole point of the sysroot feature is that it establishes a chroot
  style environment."

Note, the "chroot style environment" that he's referring to is the
equivalent of LFS Ch 6, not Ch 5.

I stand by my claim that you're abusing the sysroot option and setting a
very poor example of its use.

Sidenote: Now that some toolchain devs are apparently using *native*
sysroot builds, there is a temptation to pursue a whole new build method
that bypasses most of Ch 5. However, we would most certainly lose a lot of
the advantages of the current 2-phase approach, so gut instinct tells me
this won't be viable. Obviously, ICA verification would be *critical* to
such a build method.
