[Buildroot] [PATCH 0/4 v2] Add ability to generate some graphs

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

Hello All!

Here is a small series that adds some graphing abilities to Buildroot:
  - graph build-times, originally by Thomas, revamped now that our step-hooks
    generate $(O)/build/build-time.log for all builds
  - expose this, graph-depends and <package>-graph-depends as make targets
  - allow generating either PDF or PNG graphs

Regards,
Yann E. MORIN.

Changes v1 -> v2:
  - add --input to graph-build time  (Thomas)
  - move %-graph-depends to package/pkg-generic  (Thomas)
  - document <package>-graph-depends  (Thomas)
  - document GRAPH_ALT and GRAPH_OUT in manual  (Thomas)
  - misc typoes

Regards,
Yann E. MORIN.

      Makefile: expose target 'graph-build' to generate the build-time graphs
      Makefile: expose 'graph-depends' to generate a graph of the dependency tree
      graphs: support generating png graphs
