[Buildroot] [pull request v2] Pull request for branch yem/instrument-build

[Yann E. MORIN <yann.morin.1998@free.fr>]

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

Hello All!

This series is an RFC to add support for instrumenting the build process,
reworked after discussion both on the ML and during the developpers' day.

It works as thus;
  - we register a set of hooks
  - hooks are called before and after each steps

There are currently two hooks defined:
  - log steps with timings  (as an example of hos to do a hook)
  - call a user-supplied script

This is just a RFC for now, and if it is accepted, new hooks can be
defined later on.

I'm planning on adding at least one other hook, that runs all scripts
present in support/step-hooks/ (or whatever its name).

Open for comments! ;-)

Changes v1 -> v2:
  - removed the intra-steps instrumentation  (Thomas, Peter)
  - accept a list of user-supplied hooks, not only one hook  (Thomas)

Regards,
Yann E. MORIN.
