The graph-depends script calls make. If the outer make was called
recursively, or if it was called with '-C <somedir>', then the
environment will contain "MAKEFLAGS=w --". Therefore, the recursive
make prints 'Entering' and 'Leaving' messages, which clobbers the
output for dot.
To avoid this, add "--no-print-directory" to the recursive make
arguments. Since we require GNU make 3.81, we can be sure that this
option is available.

Merge the redundant-dependencies elimination into the newly introduced
transitive-dependencies elimination.
This makes the code cleaner and much shorter, because:
- the ('all',pkg) redundant dependency is in fact a transitive
dependency, and we now have code to deal with that
- the (pkg,'toolchain') dependency is easy enough to deal with that
having a separate function for that is overkill

Currently, all the dependencies of a package are drawn on the dependency
graph, including transitive dependencies (e.g. A->B->C and A->C).
For very big graphs, with lots of packages with lots of dependencies, the
dependency graph can be very dense, and transitive dependencies are
cluttering the graph.
In some cases, only getting the "build-order" dependencies is enough (e.g.
to see what impact a package rebuild would have).
Add a new environment variable to disable drawing transitive dependencies.
Basically, it would turn this graph:
pkg1 ---> pkg2 ---> pkg3 -------------------.
|\__________/ \ \
|\____________________ \ \
| \ \ \
`-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8
\__________/
into that graph:
pkg1 ---> pkg2 ---> pkg3 -----------.
| \
`-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8

Al packages depend on 'toolchain'. Currently, 'graph-depends' graphs this
dependency. The resulting graph is thus cluttered with less-than-useful
information.
Instead, do not graph the 'toolchain' dependency for any package, save
for the fake 'all' package. The graph is now a bit more readable.

Currently, the complete dependency chain of a package is used to
generate the dependency graph. When this dependency chain is long,
the generated graph becomes almost unreadable.
However, it is often sufficient to get the first few levels of

Currently, we are using a crude, ad-hoc parsing of argv[].
This is a limiting factor to adding new options.
Use argparse instead, and introduce a single argument for now:

such as depth-limiting for big graphs.

We ran into a "Login incorrect" problem when running the same rootfs
image across platforms with different loging ports ttyS0/1/2/3.
Simply assignning "console" to BR2_TARGET_GENERIC_GETTY_PORT, which in
turn modifies the /etc/inittab, is not enough because the "console" device
was missing in the /etc/securetty.
While current securetty has enumerated a lot of ttys, this patch should save
some efforts to enumerate more.

Until now, graph-depends was calling "make <pkg>-show-depends"
individually for eack package, which was very slow. Now, it calls
"make <pkg1>-show-depends <pkg2>-show-depends ... <pkgN>-show-depends"
for all packages it knows, and then does that recursively. It reduces
the number of make invocations to the deepest dependency chain in the
current configuration, instead of having a number of make invocations
equal to the number of enabled packages.
For a configuration with xvkbd enabled (which brings a significant
number of X.org dependencies) and a tar root filesystem, the time to
execute graph-depends was:
real 5m14.944s
user 4m53.590s
sys 0m14.069s
After our optimizations, it is now:
real 0m33.096s
user 0m30.878s

When doing a full graph of the dependencies, graph-depends starts by
doing a "make show-targets", which lists all the packages registered
in the $(TARGETS) variable. This variable contains all packages that
are enabled according to the .config file. Then, for each of those
packages, we used to create a "all" -> "package" dependency, even if
in fact most of some packages are already dependencies of other
packages. This creates a needlessly complex dependency graph.
This patch modifies graph-depends so that it filters out the unneeded
"all" -> "package" dependencies when "package" is already the
dependency of another package.
For example, if you have a configuration with libpng (which selects
zlib), "make show-targets" displays "libpng zlib", so graph-depends
used to create the following dependencies: (all -> libpng, all ->
zlib, libpng -> zlib). However, the (all -> zlib) dependency is not
really needed, as zlib is already the dependency of libpng. Those
dependencies are now filtered out.

graph-depends calls make to get the list of packages, and the
dependencies of each package.
When called out-of-tree, the Makefile is a wrapper that calls
the real Makefile, so make will spit out a line like:
make -C /path/to/buildroot O=/path/to/build-dir show-targets
which graph-depends wrongly believes is part of the target list.
Be silent when calling make, as we really only want the target
and dependency lists.
