0dc940cdee Makefile: introduce KSTRIPCMD to strip kernel modules
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.

8101c9a357 linux: strip installed modules
The installed kernel modules should have useless build cruft stripped out
of them.  On my system, a default build went from a very unreasonable 30MB
to a normal 3MB (on disk) and from 14MB to 3MB when compressed due to the
info stored in the kernel modules alone.

22c2c6b541 Makefile: handle host packages for make source / make external-deps
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.

5f71fc1f19 Remove support for shared configuration cache
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.

aefad5317f Makefile: generate a Makefile wrapper in $(O)
If building out-of-tree, add a Makefile wrapper that calls-out to the real
Makefile with proper args.

Avoids having to pass -C and O= every time we call make.

This is highly inspired from how the Linux kernel does it, and portions of
it have been used. We can't use exactly the same implementation as the
kernel does, because:

 - the script writing the wrapper has been expunged of the few lines
   that were too kernel-related: in buildroot we do not need the version
   string in the wrapper, and we do not have a patchlevel version;

 - "in-tree build" does not have the same meaning for the kernel and for
   buildroot: for the kernel, $(O) point to the $(TOPDIR), while for
   buildroot $(O) points to $(TOPDIR)/output.

For more complete explanations, see:

d147b81fda Re-implement the source-check and external-deps targets
The new DL_MODE variable dispatches between the various download
implementations of each method (Git, Subversion, Wget) to deal with the
normal download (default mode, 'DOWNLOAD'), the source-check
('SOURCE_CHECK') and to show the external dependencies for external-deps
('SHOW_EXTERNAL_DEPS').

For the latter, the legacy script wget-show-external-deps.sh is no
longer required as $(WGET) isn't called directly anymore but always
through the DOWNLOAD helper.

0b36880085 Ensure that all config-related files are generated before the build
The previous commit has removed calls to conf_write_autoconf(), which
is the function that generates the KCONFIG_AUTOCONF,
KCONFIG_AUTOHEADER, KCONFIG_TRISTATE files and the split config (with
one file per config item). Therefore, those things were not generated
anymore before the build.

In order to get them generated before the build, we use the same
mechanism as the kernel: run a silentoldconfig when the .config file
is newer than the KCONFIG_AUTOCONF file.

In Buildroot, all those elements are not really used today, except the
split config which is used a little bit in the toolchain build, in a
try to make sure the toolchain gets rebuilt properly when the
configuration changes. It does not seem that this work has been
completed.

However, as we want to keep the same behaviour as previously, we have
to generate all those elements before starting the build.

7c524dd0b6 Clean up our patches against kconfig
Our kconfig-to-buildroot2.patch hasn't been kept up to date with all
the changes made into package/config, and a single patch wasn't very
practical to maintain all our changes. Therefore, this commit adds a
package/config/patches directory, which contains a Quilt series of
patches that correspond to our modifications to the kconfig mechanism.

The huge kconfig-to-buildroot2.patch has been split into 16 smaller
patches. The purpose of some of the modifications has been clearly
identified, while some others were not identified.

The 16 patches together do match exactly the old
kconfig-to-buildroot2.patch. We have been very careful in making sure
that we wouldn't loose any of our modifications.

The only modifications made are :

 * Instead of renaming the kernel Makefile to Makefile.kconfig and
   naming the Buildroot Makefile just 'Makefile', we instead keep the
   original package/config/Makefile from the kernel
   scripts/kconfig/Makefile and name the Buildroot Makefile
   package/config/Makefile.br. The main Buildroot Makefile is modified
   accordingly.

 * The documentation README.buildroot2 is updated to explain how to
   upgrade to a newer version of scripts/kconfig.

 * The kconfig-language.txt documentation is removed, as anybody can
   easily find it in the kernel sources so there's no need to
   duplicate it here.

ed0200993e toolchain: move makefile includes
Including a bunch of Makefiles with wildcard makes it impossible to add
new toolchain backends. Avoid that by namely including needed files.

The external toolchain still needs to include all the toolchain/*/*.mk
sub-makefiles, as they are needed to build a toolchain that runs on the
target. It is to be noted that the cross-toolchain is not built in this
case, as the make-targets to build the cross-toolchain are not present
in the $(BASE_TARGETS) variable, which is later used to create the
dependency rules.

Also, the comment 'Explicit ordering' has been removed, as it is mis-
leading. It is make's responsibility to create the proper ordering based
on the dependency rules it finds in the Makefiles

2691d80803 Makefile: fix make <blah>_defconfig
Make sure we only pass O=<path> if we were originally called like that,
otherwise we might end up looking for the .config in the wrong place.

Likewise, when changing between using O= or not (or simply running
make <blah>_defconfig in a pristine source tree), we do end up having
a .config, but no .config.cmd. It isn't really critical so just continue
even if we couldn't read it.

26b44b2b02 toolchain: prepare for more than two alternatives
Lay down the path to add more than two toolchain kinds:
- check the type of toolchain as:
    ifeq (toolchain_buildroot,y)
        blabla buildroot-specific
    else ifeq (toolchain_external,y)
        blabla external-specific
    endif

- prefer using positive checks, a-la:
    ifeq (foo,y)
  instead of:
    ifneq (bar,y)
  (where foo and bar are mutually exclusive)

- have the toolchain_buildroot case always appear first

- gettext is handled differently, because we want to add an option
  only if not using the buildroot toolchain, hence we use ifneq.

If CDPATH is set in the environment, cd <dir> will print the absolute path

up as <path> <path> which breaks basically everything).

Fix it by clearing CDPATH. Notice that export doesn't affect the environment

397fe5cc0b Remove the "project" feature
The "project" feature was designed to allow to several projects to be
built inside the same Buildroot source tree and allowing the toolchain
and non-configurable packages to be shared between the different
projects on the same architecture. While being interesting in theory,
this feature adds a level of complexity to Buildroot, both from an
user perspective and from a developer perspective, while one of the
main Buildroot strengh is to be simple. Moreover, this feature is only
seldomly used by our users.

From a user-level perspective, this for example allows to remove the
project_build_ARCH directory, which was very confusing. The
autotools-stamps directory is also removed, since these stamps are
back at their normal location.

Description of the changes involved :

 * project/, directory removed

 * Makefile

    - Don't include project/Makefile.in and project/project.mk anymore

    - Grab a copy of the contents of project/Makefile.in at the
      location it was imported, but remove the definition related to
      PROJECT_BUILD_DIR. The TARGET_DIR is now in
      $(BUILD_DIR)/target_dir

    - Remove the creation/removal of the $(PROJECT_BUILD_DIR) and
      $(PROJECT_BUILD_DIR)/autotools-stamps directories

    - Don't make world depends on target-host-info. This target was
      defined by project/project.mk to customize /etc/issue,
      /etc/hostname and create /etc/br-version depending on the
      project definitions. We can of course imagine re-adding such a
      feature later.

    - Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere

    - Remove the update, log and lognr.$(PROJECT) target, they were
      specific to the project feature.

 * package/Makefile.autotools.in

    - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
      configure cache

    - Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same
      directory as the other stamps (i.e, in the package directory).

 * package/Makefile.in

    - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
      configure cache

 * package/at/at.mk,
   package/busybox/busybox.mk,
   package/busybox/initramfs.mk,
   package/customize/customize.mk,
   package/linux-fusion/linux-fusion.mk,
   package/ltp-testsuite/ltp-testsuite.mk,
   package/nfs-utils/nfs-utils.mk,
   target/cpio/cpioroot.mk,
   target/cramfs/cramfs.mk,
   target/device/Atmel/DataFlashBoot/DataflashBoot.mk,
   target/device/Atmel/Makefile.in,
   target/device/Atmel/at91bootstrap/at91bootstrap.mk,
   target/device/KwikByte/Makefile.in,
   target/ext2/ext2root.mk,
   target/initramfs/initramfs.mk,
   target/iso9660/iso9660.mk,
   target/jffs2/jffs2root.mk,
   target/linux/Makefile.in,
   target/romfs/romfs.mk,
   target/squashfs/squashfsroot.mk,
   target/tar/tarroot.mk,
   target/ubifs/ubifsroot.mk

    - Replace PROJECT_BUILD_DIR by BUILD_DIR

 * target/device/Config.in

    - Do not include project/Config.in anymore

 * target/linux/Makefile.in.advanced

    - Replace PROJECT_BUILD_DIR by BUILD_DIR

    - Store the stamps file in $(STAMP_DIR) instead of
      $(PROJECT_BUILD_DIR)/autotools-stamps

 * target/u-boot/Makefile.in

    - Replace PROJECT_BUILD_DIR by BUILD_DIR

    - Remove $(PROJECT) from the U-Boot target binary name

    - Remove the insertion in the configuration of the project name as
      the hostname

    - The u-boot-autoscript target now generates
      $(U_BOOT_AUTOSCRIPT).img instead of
      $(U_BOOT_AUTOSCRIPT).$(PROJECT)

 * toolchain/gcc/gcc-uclibc-3.x.mk
   toolchain/gcc/gcc-uclibc-4.x.mk

    - Move the stamps files to $(STAMP_DIR)
