gold is not capable of building glibc/eglibc, so we have to
force using the BFD linker, ld.bfd.
Offer a blind option that affected components can select to
force use of the BFD linker during the build.

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.

There was a mishap when cut-n-pasting code from the final

In a lot of places, we need to call some commands with specific
variable settings, a-la:
var1=val1 var2=val2 /foo/bar/buz opt1 opt2
Unfortunately, we currently can not log the variable settings.
Enhance CT_DoExecLog with a crude heuristic that works pretty well
and that can also log setting variables.

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.

Doing a chmod on the whole source dir after every packages
are extracted can take a hell of a lot of time.
The offending packages are far from legion, and they now
have their own chmod u+w to cleanup their own mess...

Building the start files requires a shared-capable compiler, which we do
not have when the threading implementation is LinuxThreads.
So, only build the start files when the threading implementations is NPTL.

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...

As companion tools might or might not be used to build each
toolchain, they do belong to that toolchain's build tools,
not to the generic override tools.

There is absolutely *no* reason for the buildtools (wrappers to gcc, g++,
as, ld... for the local machine) to be in the toolchain directory. Moreover,
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.

Currently, the buildtools are installed relative to ${CT_PREFIX_DIR}.
Change that by introducing ${CT_BUILDTOOLS_DIR}, which is
still set relative to ${CT_PREFIX_DIR}, but which will make it easy
to change in the future.

The gcc used by linaro has a version number specific to Linaro, but
identifies itself with its upstream version numbering scheme.
This breaks the strip in the finish step, because the actual gcc version
is not the same as the configured one (eg. 4.5.2 vs. linaro-4.5-2011.02-0).
