Having the crosstool-NG version in the .config helps in case we
want to reproduce the toolchain with the exact same version of
crosstool-NG.
This also reverts #bb73e7632b54.

Allows to choose if one wants to keep or not the syscalls that are provided with
newlib. It passes the --disable-newlib-supplied-syscalls or
--enable-newlib-supplied-syscalls to the configure script. If one chooses to
disable the builtin syscalls, he/she will have to write his/her own. This can
be usefull to port newlib to a new platform/board.

Virtually all our targets do support stack unwinding. For some of
them, ./configure can't detect that, and the build fails later on.
So, default to force unwind, and let the user disable it if it
breaks in his/her case.
The previous changeset (f44286235a07) was empty, as spotted by Benoît.

Simplify the way the custom tarball is handled:
- fake version="custom"
- at download, simply link the custom tarball to:
"linux-custom.${custom_extension}"
- at extract, the above allows to simply extract "linux-${LINUX_VERSION}"
where LINUX_VERISON is set to the fake version="custom"
Not that much convoluted, in fact... :-/

No-one ever inquired about this feature. Due to the way it works, it is
rather unlikely that every user used a properly-formatted tarball, or a
properly structured directory as imput.
Beside, it is not really easy to maintain: I just spent one full day
remembering how it worked... Sigh... :-(
Just deprecate this, until next release, or until someone complains.

Currently, the mirror can be used either:
- as a fallback in case upstream is unavailable (default behavior)
- as the preferred source for downloads
But the most common use-case seems to provide a truely-LAN mirror
to speed up downloads in big corpos', and/or provide a 'trusted'
source for the tarballs.
So, make the following changes;
- if a mirror is specified, always try that before trying upstream

svn is needed to download eglibc from the upstream repository.
In some situations, though, it can happen that:
- the developpers' machines do not have svn
- a LAN mirror has been set-up with pre-downloaded eglibc tarballs
In this case, it makes sense not to hard-depend on svn.
So, if svn is missing, just say so, and add a comment in the
menuconfig.

Cross-gdb depends on expat and python. If either is missing, cross-gdb will
build successfully, but lacking some features.
Especially, if expat is missing, cross-gdb will be unable to parse the target
description, which may lead to runtime malfunctions and the following GDB
warning:
"Can not parse XML target description; XML support was disabled at compile time"
Hence, expat should be considered mandatory.
On the other hand, the features missing without python are not critical, so
python should not be considered mandatory.
This patch does the following:
- At configure time, warn the user if either expat or python is missing.
- In menuconfig, disable the static build options regarding cross-gdb if no
static version of expat is available, and disable cross-gdb if expat is
missing.

present, detected at configure time.
Add a blind option that says whether static linking is possible at all.
It defaults to 'y', but depends on the needed CONFIGURE_* options. For
now, it only depends on static libtdc++, but new dependencies can be
easily added.

If check_for is able to find the required prog/inc/lib, allow it to
set an arbitrary variable to 'y'. This variable is then pushed down
to the kconfig definition.
For example:
has_or_abort prog=foobar kconfig=has_foobar
If foobar is available, it yields a kconfig variable defaulting to y:
config CONFIGURE_has_foobar
bool
default y
If foobar is missing, it yields a kconfig variable defaulting to n:
config CONFIGURE_has_foobar
bool
Thus it is possible to depends on that variabel to show/hide options:
config SOME_FEATURE
bool
prompt "Some feature"
depends on CONFIGURE_has_foobar
