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.

This patch introduces a single, simple, infrastructure to build the
Linux kernel. The configuration is limited to :
* Kernel version: a fixed recent stable version, same as kernel
headers version (for internal toolchains only), custom stable
version, or custom tarball URL
* Kernel patch: either a local file, directory or an URL
* Kernel configuration: either the name of a defconfig or the
location of a custom configuration file
* Kernel image: either uImage, bzImage, zImage or vmlinux.

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.

Otherwise u-boot tools / kernel modules are only added to target AFTER

Long term u-boot/kernel stuff should get splitted from target/device,
but this is the safest solution for now.

GNU_HOST_NAME is referred more than 100 times in the tree, used 5
times during startup, and is relatively expensive to run - so make

On my target rootfs it is installed documentation for:
atk, cairo, gdk, gdk-pixbuf, gio, glib, gobject, gtk, pango
It ocupies 34M of space. Configure option --disable-gtk-doc doesn't
prevent installation of it. So we should remove them manually if
documentation is disabled.

Until now, we had BR2_HAVE_MANPAGES, BR2_HAVE_INFOPAGES and
BR2_HAVE_DOCUMENTATION, but there's no need to have such a
fine-grained control over what documentation gets kept or not.
Therefore, just remove all the documentation (man pages, info pages
and documentation in $(TARGET_DIR)/usr/doc and
$(TARGET_DIR)/usr/share/doc) when BR2_HAVE_DOCUMENTATION is not set.

Strangely enough O is still passed to submakes with MAKEOVERRIDES
(with make 3.81 atleast), the only thing that changes is the output
of the origin function (command line -> environment).
Unfortunately some packages don't look at origin (E.G. uClibc 0.9.31+)
To really make O go away, we have to override it.

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
of <dir>, causing various trouble (The most critical being BASE_DIR ending
up as <path> <path> which breaks basically everything).
Fix it by clearing CDPATH. Notice that export doesn't affect the environment
of $(shell ..) calls, so explicitly throw away any output from cd in the
BASE_DIR shell call.

As discussed on the list, fixup the *clean targets, so we now have:
clean: remove all generated files (E.G. everything in output/)
distclean: same as clean, but also remove the kconfig build and .config
Also tweak 'make help' output to match. This also merges the two
different clean / distclean targets we had depending on if there was
a .config present or not (most variables are not defined for !.config
case, so E.G. the clean target ends up being a noop).

In the output directory, we now have
- build/ where all the packages are built
- images/ where the final kernel and rootfs images are stored
- staging/ the staging directory (containing the development files
and libraries compiled for the target)
- target/ which contains the target root filesystem
- host/ which contains all the host programs
- stamps/ which contains the stamps files
Therefore, the build_ARCH and toolchain_build_ARCH have been
removed. People willing to use the same Buildroot sources to compile
for different architectures are invited to use the O= command line
option for out-of-tree compilation.

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/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)
