Adapting LFS SVN for multilib

[Nathan Coulson]

I have been using a modified LFS (built for 32/64bit at the same time)
and it worked well until the latest changes were introduced to trunk
(that use the -B flag).  Specifically GCC pass2 does not find crt0.o
32bit (just see's the 64bit).  I was curious if this is what the
buildsystem that 7.0 is going to be using, or if it is still a work in
progress.

I was a bit lost with the latest change, as to why it does not use
/tools/lib or /tools/lib64 without -B as that would allow me to use my
old work without deviating too far from LFS.
