[Buildroot] [PATCH v7 00/18] Relocatable SDK / build machine leaks

[Samuel Martin <s.martin49@gmail.com>]

Hi all,


Here is yet another round of the series aiming improving the relocatability
of the SDK built by Buildroot.

The new round improves the shell implementation started in the previous
submission.


In details:

Patches 1 to 3:
  Clean up and preparatory work for the relocatable SDK series and also helping
  to track build machine leaks into host, target and staging trees.

Patches 4 to 7:
  Make some pieces of the Buildroot SDK relocatable (limited to some symlinks
  and *-config scripts).

Patches 8 to 10:
  Add the fix-rpath script, then run it on the Buildroot host, target and
  staging trees.

Patch 11:
  Clean-up speex package WRT its RPATH hook.

Patch 12:
  Add a post-install hook to the toolchain package to render it relocatable.

Patch 13 to 15:
  Update and fix the check-host-rpath to re-use the shell helpers.

Patches 16 and 17:
  Add means to track build machine leaks into the host, target and staging
  trees. These patches will allow to identify what remains to be fixed WRT
  build machine leaks.

Patches 18:
  Update documentation about how to enable/adjust log level on script using
  the shell modules introduced in patch 8/18.


Worth noting:

* patches 4, 5, 6 and 7 fix scripts or wrappers WRT improving the SDK
  relocatability;

* patches 8 and 16 add new scripts (which are not executed without the
  patches 9, 10 and 12).

* patches 9, 10 and 12 add make targets called on all builds, improving the
  SDK relocatability; patch 17 also add make targets, but they are not in as
  dependency of any other, so must be invoke explicitly.

* all others patches are fairly trivial fixes or improvements.


Future works:

* Handling autotools/libtools relocation

* Analysing and fixing leaks and relocation remaining issues


Regards,
Samuel
