Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.
For example, ARM supports this mode (to come in the next changeset).
Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.

Change CT_ExtractGit so that it clones the repository, instead of just
symlinking it. After cloning, any given ref is checked out, or if no
ref is given, the HEAD of the repository is checked out.
This makes CT_Extract behave similar for git repositories as it does
for tarballs, so that it for example can be used for passing glibc-ports
as a git repository.

Some packages are available as LZMA tarballs. LZMA is a relatively recent
compression algorithm; it's slightly better than bzip2, but offers much
faster decompression. LZMA is now deprecated in favor of XZ, but some
packages switched to LZMA when XZ was not yet available, or still in its
infancy. Latest XZ (which totaly obsoletes LZMA) offers a backward LZMA-
compatible utility, so we can check for 'lzma' nonetheless.

./configure does check for the presence of gz and bzip2, so we can
safely use them in the build scripts.
On the other hand, more recent formats (eg. XZ) are not yet widely
available, and we do not want, and can't, force the user to install
them as a pre-requisite.
So, build up a list of allowed tarball formats based on the available
decompressors. For no, this is a static list, but the upcoming XZ
support will conditionnaly add to this list.

When downloading via svn/cvs/... an attempt to retrieve from the

an error message is printed. This is misleading, as the download

Currently, the mirror can be used either:

But the most common use-case seems to provide a truely-LAN mirror

source for the tarballs.
So, make the following changes;

The cvs download helper looks for the local tarballs dir to see if it
can find a pre-downloaded tarball, and if it does not find it, does
the actual fetch to upstream via cvs.
In the process, it does not even try to get a tarball from the local
mirror, which can be useful if the mirror has been pre-populated
manually (or with a previously downloaded tree).
Fake a tarball get with the standard tarball-download helper, but
without specifying any upstream URL, which makes the helper directly
try the LAN mirror.
Of course, if no mirror is specified, no URL wil be available, and
the standard cvs retrieval will kick in.

Some archives like those of the 2011.07 revisions of Linaro GCC contain a folder
name different from the archive basename, which leads to errors afterwards, e.g.
when patching. E.g.:
gcc-linaro-4.5-2011.07.tar.bz2 extracts to gcc-linaro-4.5-2011.07-0/
This patch changes CT_Extract() to force the extraction of all archives to a
folder named like the archive basename. E.g.:
gcc-linaro-4.5-2011.07.tar.bz2 now extracts to gcc-linaro-4.5-2011.07/

In case of eglibc, some add-ons that were previously external are
now internal (bundled with the main sources).
So we do not want to fail if an add-on can't be downloaded; we
want to post-pone the check until we can extract the main archive.
So:
- try to retrieve the add-on
- if it fails, print a warning instead of calling CT_Abort
- return 1
So, components that want to catch the error and want to handle it can,
while components that do not will gracefuly fail thanks to our catching
every errors.
Bonus: it works without changing any existing retrieval procedure! :-)

Managing the shared version of the companion libraries
has become cumbersome.
Also, it will one day be possible to use the companion
libraries from the host distribution, and then we will
be able to easily use either shared or static libs.
As a side note, while working on the canadian-rework
series, it has become quite more complex to properly
handle shared companion libraries, as they need to be
built both for the build and gost systems. That's not
easy to handle. At all.

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.

There is absolutely *no* reason for the buildtools (wrappers to gcc, g++,

they are removed after the build completes.
Move them out of the toolchain directory, and into the build directory (but
yet the part specific to the current toolchain). This means we no longer
need to explicitly remove them either, BTW, but we need to save/restore them
for the restart feature.

Download to an intermediate temp file, and rename it to its final

This catches both a failed download, and also the case where the user
