The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.
This patch therefore removes the shared configuration cache
infrastructure and usage.

Supporting multilib is much more than just passing --enable-multilib
to gcc. You have to actually build the C library several times (once
for each multilib variant you want to support in your toolchain), and
to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it
know the set of multilib variants you're interested in.
Since we'll probably never support multilib toolchains in Buildroot,
just get rid of this BR2_ENABLE_MULTILIB option.

This is a very advanced option, and it seems, according to
http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't
really interesting.
Users really interested by this can always use the
BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.

The buildroot/busybox/uClibc VM is running low on disk space, and we've
been asked to move the source mirrors off-site.
A redirect has been setup between the old buildroot.net/downloads/sources/
and sources.buildroot.net, so old .configs continue to work, but we might
as well use the official one now.

We only bother updating the defconfigs that need a non-default
BR2_ROOTFS_DEVICE_TABLE value.

Use the new default STAGING_DIR location (output/staging) in all the
defconfigs for clarity.

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.
