gcc-4.6+ requires the Parma Watchdog Library (libpwl).
Build it and use it.

So far, we've had a version always select appropriate _or_later option,
which in turn would select all previous _or_later options.
Because the dependencies on companion libs were cumulative, that was
working OK. But the upcoming 4.6 will no longer depend on libelf, so
we can't keep the cumulative scheme we've been using so far.
Have each release family select the corresponding dependencies, instead
of relying on selecting previous _or_later.

There was a mishap when cut-n-pasting code from the final
step into the core step: a variable was not renamed.

Some scripts have 'very long lines', so the output of 'file'
will have that mentioned, such as:
POSIX shell script, ASCII text executable, with very long lines

In a lot of places, we need to call some commands with specific
variable settings, a-la:
var1=val1 var2=val2 /foo/bar/buz opt1 opt2
Unfortunately, we currently can not log the variable settings.
Enhance CT_DoExecLog with a crude heuristic that works pretty well
and that can also log setting variables.

Users tend to look for the build log in the current working directory,
rather than in the toolchain's installation dir. While bundling the build
log in the toolchain installation dir is nice for distribution and review,
it can be easier to have the build log readily available in the working
directory, as it is quicker to get to it.
So, the build log stays in the working directory until the toolchain is
completely and successfully built, and then a (compressed) copy is made.

Doing a chmod on the whole source dir after every packages
are extracted can take a hell of a lot of time.
The offending packages are far from legion, and they now
have their own chmod u+w to cleanup their own mess...

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:

Plugins are shared objects, and when building a toolchain statically,
the gcc build system breaks havok (although there is no hard technical
reasons it should not be possible)...
And consequently, do not enable plugin supoprt in binutils.
