The latest kconfig stuff is more stringent when it comes to validating
the dependency of the symbols. It is no longer possible to have a symbol
depend on itself (such as our construct for arch/cc/libc/... was doing).
Fix our generated-file infrastructure to avoid these situations when the
new kconfig stuff will be merged (in a following changeset).

Since the gcc configuration changes, the way to select the
dependent companion libraries has changed. The addToolVersion
script was not updated to match, and a new gcc version was
added with this script.
Fix the gcc version; the script will be updated in a subsequent
changeset.

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.

Add support for building SPARC targeted toolchain.
With this patch I have built a working sparc V8 (32 toolchain).
Testing shows that not all gcc versions works well:
4.4.1 OK (kernel builds and the final kernel can boot)
4.4.2 Not tested
4.4.3 Not tested
4.4.4 BAD (Kernel can build but fails during boot)
4.4.5 BAD (Kernel can build but fails during boot)
4.5.1 BAD (Build fails with a spill related ICE - http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35664)
4.5.2 OK (kernel builds and boots)
I have successfully been using the 4.5.2 version for a few months.
This patch does not add support for the LEON variant.
That may come later.

PPL 0.11+ installs three libs: lippl, libppl_c and libpwl.
libppl_c has a dependency on libpwl (at least for watchdog stuff).
While gcc correctly links with libppl and libppl_c, it does not
pull libpwl in. In case of shared libs, this is not a problem, as
libppl_c has a NEEDED dependency on libpwl. But for static libs,
that does not work. Although libppl_c.la exists and has a correct
dependency on lipwl, somehow gcc misses it. So we have to force
pulling libpwl when needed.

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.

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.

By default, recent versions of glibc and eglibc will build some
functions that take format strings (eg. printf, syslog...) with
run-time checks against some format string attacks. This is
called a fortified build.
Unfortunately, this fails somehow while building the instrumented
version of syslog, with some kind of circular dependency...
Disable fortified builds by default, and hide the enabling option
behind EXPERIMENTAL for daring users...
