The current implementation of buildroot depe dependency graphing
either does forward- or reverse-dependency traversal.
This patch enables buildroot to graph forward and reverse dependencies
on the graph for the same package: (Diagram Credit: Yann E. MORIN)
$ make pkg-d-graph-both-depends
pkg A -. .-> pkg E
\ /
pkg B ----> pkg D ----> pkg F
/ \
pkg C -' '-> pkg G
In the above example a single graph shows pkg {A,B,C} are needed
by pkg D, and pkg D is a dependency of pkg {E,F,G}.
Makefile help and manual are also updated.

[Arnout:
- remove DEPTH and RDEPTH, their functionality is already covered by
BR2_GRAPH_DEPS_OPTS;
- remove --rdepth, it was felt to not add sufficient added value;
- add the new target to the manual;
- fix flake8 errors.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
