The wildcard function in make 3.82 no longer sorts the output, so
add an explicit sort so the defconfigs are listed in a sensible order.

'source-check' breaks because the *_DEFCONFIG options are empty strings.
There is an explicit check to avoid erroring-out when doing 'source', but
not when doing 'source-check'.
This patch set DL_MODE right from the first sub-make call.

Now that we use a wrapper for external toolchains (and internal ones
default to the correct setting), we no longer need to explicitly pass
sysroot/march/mtune/mabi/floating point mode in TARGET_CFLAGS.

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.
With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.

When ccache support is enabled and 'make silentoldconfig' is being
started from the following rule:
$(BUILD_DIR)/buildroot-config/auto.conf: $(CONFIG_DIR)/.config
$(MAKE) $(EXTRAMAKEARGS) HOSTCC="$(HOSTCC_NOCCACHE)" HOSTCXX="$(HOSTCXX_NOCCACHE)" silentoldconfig
then, the Makefile in package/config inherits from HOSTCC/HOSTCXX
values with the ccache prefix. However, if we start from a cleaned
build (after make clean), ccache is not compiled yet, so things break.
To solve this, we pass a noccache variant of HOSTCC/HOSTCXX down to
the package/config Makefile.

The current code accidentally sets up HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE
only when the respective HOSTCC or HOSTCXX values are not set. So if you
do something like:
make HOSTCC=gcc menuconfig
The build fails because HOSTCC_NOCCACHE is not set anywhere.

Allow the user to define HOST_DIR in the config menu.
This way when building an internal toolchain a separate (maybe shared)
output directory may be defined and the toolchain can be used by
multiple users and/or projects.

Instead of letting the user define all the details of his external
toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).
Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.
We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

When sstrip is selected it tries to strip kernel modules too.
Unfortunately this fails with a "unrecognized program segment header
size" error thus interrupting the build process.
We introduce a new $(KSTRIPCMD) strip command for this, being a regular
strip when sstrip is selected and an empty stub when not stripping.
At the same time get rid of the REMOVE_SECTION_* variables, as they are
only used once.

Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.
This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.
Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.
Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

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.
