rand{,package}config enables configuration options with 50% probability,
which isn't always what we want in BR (because the "big" configs take a
long time to build and limits the chance of a randconfig detecting a
missing dependency), so introduce a KCONFIG_PROBABILITY environment
variable to tweak the probability between 0 (all options off) and 100
(all options on).
To use, simply set the environment variable before running make or pass
it on the make command line - E.G.
make randpackageconfig KCONFIG_PROBABILITY=10

We don't actually need to explicitly clean the kconfig stuff, as distclean
already removes the entire BUILD_DIR, but fix up the packag/config makefile
to do the right thing if make clean/distclean is called manually for
completeness.

Support the GTK variant of the graphical kconfig configurator as an
alternative to the Qt3-based one.

Since the recent update of Kconfig to the Kconfig infrastructure found
in 2.6.30 kernels, make oldconfig was broken because it didn't
generate the .config.cmd file. This is done by a call to the
conf_write_autoconf() function.
Moreover, this process was also broken because the
conf_get_autoconfig_name() function was reading the environment
variable BUILDROOT_AUTOCONF while the main Makefile is passing it as
KCONFIG_AUTOCONFIG. We also remove the fallback on
"$(BR2_DEPENDS_DIR)/config/auto.conf" since we are not able to expand
BR2_DEPENDS_DIR at this point. Therefore, the KCONFIG_AUTOCONFIG
envionment variable *must* be set.

The update of kconfig and the addition of xconfig support generates
more files in package/config/. Tell git to ignore them.

It involved:
* Modifying the top-level Makefile to create the xconfig target, and
the $(CONFIG)/qconf target to compile the qconf utility
* Modifying the package/config/Makefile magic so that C++ files and
binaries gets linked properly, re-using the
package/config/Makefile.kconfig logic inherited from the kernel
* Hacking a little bit package/config/Makefile.kconfig in a way
similar to the modifications done for the mconf (menuconfig
interface)

Don't use this, it doesn't work yet. Thoughs welcome.
Like: We should probably use the sym->text and not fiddle with the name since
the name looses information ('_' != '-' in host-fakeroot). This would not
be too robust, i fear, since the name can contain additional, arbitrary info.
Also, the real 'depends' are a little bit ugly in kconfig. There doesn't seem
to be a nice property that holds reverse deps that are only contain selected
symbols.
Thoughts?
This also provides a nice up-to-date filestamp if something got reconfigured (e.g. c++ support got toggled) that can be used in the future to depend accordingly.
