ffe80db73c libc: get rid of libc_finish
At long last, we no longer have any libc that requries a libc_finish.
Yeah!

c8e39d6d29 configure: use autoconf to generate configure
Create configure.ac, an autoconf script to generate ./configure
This will be needed by a subsequent patch to properly handle
--build and --host, and more tests, when the kconfig stuff will
be installed pre-built.

5f41858c75 docs: credit Konrad EISELE for the initial multilib support
Konrad submitted an initial patch adding multlib support:
    http://sourceware.org/ml/crossgcc/2011-11/msg00040.html

The patch was full of good ideas, but had a few issues, so
I (Yann E. MORIN) started it all from scatch, re-using part
of the original patch. This got implemented in this series:
    hg log -r 446a17b5dd1e:e47d17391ae3

As I forgot to credit Konrad in these changelogs, update the
docs so that the work by Konrad gets credited. Without his
initial effort, we would probably not have had multlib support
so soon. Thank you Konrad!

949254a2e7 docs: --target versus --host
In the very beginnings, eons ago, autotools also got confused by this
whole build vs. host vs. target, and got it wrong. Now they fixed it,
but they want to keep backward compatibility, so the --target is still
recongised, although ./configure will complain if you do so. It is
better to use --host.

dd6ea2508a docs: add an in-depth explanations of the build steps
The build process is quite complex: gcc is built three times, there are
two C library steps, there are those companion libraries...

People often wonder what all these steps do, and why they are needed.

Recently, someone proposed a tutorial on the crossgcc mailing list:
  http://sourceware.org/ml/crossgcc/2011-01/msg00059.html

This meant that there was a need for such a tutorial, and explanations
on how a toolchain is built. So i decide to extend my answers:
  http://sourceware.org/ml/crossgcc/2011-01/msg00060.html
  http://sourceware.org/ml/crossgcc/2011-01/msg00125.html

into proper documentation in crosstool-NG.

Thanks go to Francesco for suggesting this. He has a fine tutorial
for beginners there:

have the sysroot be named differently than the hard-coded name.

Add an option for that.
Default to 'sysroot' to match the existing literature.

While at it, replace 'sys-root' with 'sysroot' everywhere we
reference the sysroot.
