Add more notes to old bootstrap builder procedure.
NOTE: This procedure DOES NOT WORK. I tried to avoid some ugly patches
and build system modifications that LFS uses by doing a sysroot build.
I messed up by not configuring GNU Binutils for a sysroot setup. But
this procedure is still kind of ugly anyway, so we'll be following a new
one based on Cross Linux From Scratch - Sysroot.
