On some systems (e.g. Fedora 20), the build breaks when parsing include

show-targets is only used currently by the graph-depends script, which
already recurses into the dependencies of the selected packages to
build the dependency graph. Therefore, dumping the contents of
$(PACKAGES) and $(ROOTFS_TARGETS) is sufficient: $(HOST_DEPS) and
$(TARGET_HOST_DEPS) will contain packages that are dependencies of
packages already listed in $(PACKAGES), which graph-depends will
discover by itself.
This allows to remove one more usage of $(HOST_DEPS) and
$(TARGET_HOST_DEPS), which is one more step towards their removal.

This commit changes the implementation of the global 'legal-info'
target to use the newly introduced per-package <pkg>-all-legal-info
target. This allows to avoid using the $(TARGET_HOST_DEPS) and
$(HOST_DEPS) variables that we are trying to remove.
It is worth mentionning that this commit might change the output of
'make legal-info' by making it more correct than it was. With the
existing implementations, we could be missing packages if they were
host packages, or target packages not properly selected in terms of
Config.in dependencies, and with a more than a two-level deep
dependency from a target package properly selected at the Config.in
level. This is because our previous logic was simply taking all
packages in the "TARGETS" (now called "PACKAGES") variable, which are
only the target packages explicitly selected in the .config file, and
doing a two-level deep recursion in the dependencies.
With this commit, we switch legal-info to use proper make-based
dependencies, so we no longer have the limitations we used to
have. For this reason, the output of 'make legal-info' after this
patch may contain *more* entries than before this patch, but it is
really because it is now correct.

In 8a46d4bf1f the randpackageconfig and allpackageyesconfig were
extended with disabling all the legacy options, otherwise the resulting
config couldn't be built. However, that didn't work for randconfig and
allyesconfig.
This commit reverts 8a46d4bf1f and replaces it with a different
approach: skipping of the legacy config options is passed explicitly
through the environment variable SKIP_LEGACY, which forces
BR2_SKIP_LEGACY to y. The new option BR2_SKIP_LEGACY completely
disables the legacy handling, which effectively removes all the legacy
options from the .config.
However, in that case no values are set for the legacy options so a
subsequent oldconfig will query them. Therefore, run an additional
olddefconfig.

This definition of HOSTFC is completely wrong.
"$(HOSTLD)" should be "$(HOSTFC)". Also, "echo" always succeeds, so
"which g77 || type -p g77 || echo gfortran" is never run.
Anyway, HOSTFC is most likely set to "/use/bin/ld" and nobody has
complained about it before me, so I guess it is not used at all.
At least grepping HOSTFC, FC_FOR_BUILD did not hit any packages.

`command line'

Therefore, $(origin V) will get a value anyway, killing ifdef/endif

Furthermore, I've checked the minimal requirements from the top
Makefile is GNU make 3.81, and that version of GNU make has support
of origin function well already, so now it's safe to kill the outer

sense. PHONY targets are targets that do not exist on the filesystem,

the commands associated to these targets are always executed by make
when the command is invoked, even if a file with the same name exists

Special characters in files or directories in the rootfs can cause
problems when stripping files. For example "target/some song.mp3"
gets treated as two entries. "target/some" and "song.mp3" are both
passed to $(STRIPCMD). This then errors saying files don't exist.
Additionally a ' and possibly other special characters in a file path
causes xargs to give the error: "xargs: unmatched single quote; by
default quotes are special to xargs unless you use the -0
option". This also has the effect of removing this entry and further
entries from the list of files to strip. This can be demonstrated by
having a test directory with the files: "cat" "rabbit's"
"elephant". then running the command: "find -name "*" -print | xargs"
To fix this we pass -print0 to find which seperates entries with a
NULL character, and we pass -0 to xargs to tell it to only use NULL
characters as the deliminator.

We have the BR2_DEFCONFIG feature that saves the path to the defconfig
file that was specified on the command line, so that a later
savedefconfig would immediately save to the right location. This wasn't
done for the defconfigs in the configs/ directory, however, to avoid
accidentally overwriting them.
Now we decided that it would be more useful to overwrite the defconfigs
in the configs/ directory after all. To do this, we pass the path to
that defconfig in the environment.

Buildroot unexports PKG_CONFIG_PATH in the top-level Makefile for purity
reasons. But it has an unfortunate side-effect in that "make menuconfig"
will not (necessarily) be able to pick up ncurses via host pkg-config,
breaking "make menuconfig" on systems where ncurses is installed in a
non-standard location.
This patch saves the original PKG_CONFIG_PATH variable in
HOST_PKG_CONFIG_PATH and restores the original PKG_CONFIG_PATH variable
only in the sub-processes that builds the various menuconfig/nconfig/...
targets.
(PKG_CONFIG_PATH has to be placed in front of the make command so that it
propagates to sub-processes. If given as an argument, it doesn't work.)

The GENERATE_LOCALE variable is used for the qstripped version of
BR2_GENERATE_LOCALE. It was used by both the glibc locale generation
code (in the main Makefile), and by the uClibc logic in
package/uclibc/uclibc.mk. However, since commit
33de740170 ("Makefile: convert
"target-generatelocales" to a hook"), this code has been moved around
in the main Makefile, and the definition of GENERATE_LOCALE is now
*after* uclibc.mk is included, and therefore this variable is always
empty when uclibc.mk looks at it for its conditionals. Moreover, it is
now only defined in the main Makefile is BR2_TOOLCHAIN_USES_GLIBC is
'y', which obviously isn't the case for uClibc toolchains.
Since it's anyway not very clear to have this variable shared between
the glibc locale generation logic in the main Makefile and the uClibc
configuration code in uclibc.mk, this commit:
- Renames the GENERATE_LOCALE variable in the main Makefile to
GLIBC_GENERATE_LOCALES.
- Renames the GENERATE_LOCALES hook to GENERATE_GLIBC_LOCALES, since
it's specific to glibc.
The fix for the uClibc case is part of a followup commit.

Currently, the only way br2-external may generate a document is by
including that document's recipe from within external.mk.
But external.mk is only parsed when the tree is configured.
This is unlike our internal document (the manual) which can be generated
from within an unconfigured tree.
So, include the documents from br2-external at the same time we include
our own document:
- expect the same layout as we have: docs/DOC_NAME/doc-name.mk
- do not fail if there is no document: use "-include", not "include"

Ideally, this new file should better go in docs/ rather than in package/ .
However, docs/ is already full of our website stuff, so adding it in
