Add support code for the canadian-cross case.

Add implementation for a candadian build option already
present in crosstool in order to build a cross-compiler
where build != host != target

[samples] Make saveSample.sh a little bit more generic

Prepare saving canadian samples by making the saveSample.sh script
a little bit more generic, using conditional code-paths (even if
there's currently a single code-path).

Don't use prefix/bin to install the buildtools.

Collect the build tools in a seperate folder in order to prevent accidental
calling our newly build tools.

Fix MPFR build to recognise the Mingw32 case.

Once we have canadian in place, Mingw32 can be a legitimate host,
so we have to recognise that along with Cygwin.

Also fix recognising Cygwin hosts.

Use configured shell in all build-tools wrappers

Abide by the user's wish to use dash as shell in
build-tools wrappers, instead of plain /bin/sh.

Fix creating the .../lib/ directory structure in the non-sysroot case

The symbol link that is created in the sysroot directory only needs
to be made when the cross compiler is build with the sysroot option

Also set CT_DEBUGROOT_DIR for non sysroot-ed toolchains.

In the non-sysroot-ed case, the debuf-root directory would not be set;
debug tools would have been installed God-only-knows-where...

[tools] Update config.guess and config.sub

Update from upstream.

Remove left-over debug lines.

Remove two lines of code that were commented out and are definitely not used.

Check paths sanity before they get used.

Don't use the PATHs before they get checked for sanity.

Better check for spaces in paths

Spaces are evil in paths. Print the path that contains a sapce.
Don't print computed paths, as they'rebased on provided paths,
and don't get space added into them.

[functions] Allow newlines (\n) in log messages

Allow caller to log messages with embedded newlines when calling
CT_DoLog and other logging functions (eg. CT_Abort...).

[finish-step] Fix the tools wrappers

Use the correct variable when iterating upon the tools
name to correctly link the tools to the wrapper.

Add .hgignore file.

List all generated or temp files in .hgignore, so they
don't clutter the screen when running hg status.

Merge the gcc-4.4 support.

[gcc] Merge the gcc-4.4 suport to the default branch, from 1407:83083566fdd0

[configure] Use hg to compute the version string

Now that we have migrated to hg from svn, it does not make sense
to keep using svn tools to compute the version string, so switch
to using mercurial tools (that are much more flexible, BTW).

[finish-step] Use local variable in finish-step

When wrapping the tools, use a local variable when iterating.

[companion-libs] Fix spaces in help entries

Some help entries were missing proper alignment-spaces.

[populate] enhance documentation

This patch adds explanations on how
populate works internally.

[populate] fix documentation

This patch fixes the existing documentation:
- document -l and -L
- use syntax more in line with the help entry
