The Kconfig menu "Pixel depths" of Qt provides a list with all
selectable pixel depths and additionally the option "all".

When "all" is selected, the list with all available pixel depths

Because this disappearing of available pixel depths makes no sense
under usability aspects, simply remove the option "all".

wpa_supplicant: adjust make environment for pkg-config call

In case that wpa_supplicant is configured with DBus interface,
it calls pkg-config to find the dbus headers and libraries.
Adjust the make environment so that it will use the right
pkg-config search paths.

buildroot; move defconfigs to configs/ and print in help

As discussed earlier on the mailing list. It simplifies code, gives more
sensible error message on typos and makes the defconfigs easier to find
for users.

Furthermore, update documentation to match.

Makefile: add rand/allyes/allno package config targets

Similar to the normal targets, but only affects the BR2_PACKAGE_* options.
E.G. handy for keeping your current toolchain config while testing
(random) packages.

Furthermore, get rid of the unused tags target.
