misc: change references to point to the new website

It's been a while now that crosstool-NG has been hosted on it's own
website, and not at my home. Change every reference to the old site
to the new one, everywhere is makes sense to.

samples: update to latest set of options

Update all the samples, so that there is not config-prompt when
recalling samples. This is no upgrade, it's just about having
new options set (y or n) in the samples.

Also, get rid of the armeb-test_nptl-linux-uclibcgnueabi, it's no
longer needed, there's a non-test sample with uClibc NPTL, now.

scripts/functions: Fix CT_ExtractGit function.

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.

scripts: check host features with host compiler

Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.

So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

Even if the current process is highly parallel, crosstool-NG spends most

1 to 3; that is crostool-NG spends two-thirds of its time running
non-parallel jobs).

debug/gdb: we don't care if the host tic is shared or static

Because we need our own host tic, we have to build it; and we do build
it statically for now.

But as MacOS/Darwin/Whatever-you-call-it does not support static linking
(what a shame!), it fails.

Anyway, we don't really care it being shared, in the end.

With the upcomming --program-{prefix,suffix,transform-name} options,
we'll have a need to centralise the actual executable name, that is

Rather than spread the prefix/suffix through-out the code, just
centralise the name setting in one place. Beside, transform-name
would not be possible without setting the name at a single location.

scripts/functions: test for decompressors before use

./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.
