[Buildroot] [PATCH 0/6 RFC] toolchain/external: use generic extract commands (branch yem/extract-cmds)

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

Hello All!

This series is an attempt at simplifying the way external toolchains are
extracted.

Currently, external toolchains use custom extract commands, because they
want to exclude a bumch of files during extraction, so as to save a bit
of space (locales in some toolchains can account for up to 80% of the
size of the toolchain as a whole).

And it turns out, gcc also wants to exclude a bunch of files (java and
go, testsuites).

Using custom extract commands means that those packages (and critical
ones, at that) can not benefit from the enhancements and fixes made to
the generic commands, like the automatic triiping of components.

In this series:

  - we first introduce the support for the exclusion list
  - we always break/dereference hardlinks
  - we make gcc use the exclusion list
  - we then make the external toolchains use it (in two passes: one for
    the non-Blackfin case, one for it, as it is 'seecial')
  - finaly, we introduce the Codescape MTI toolchain from Vincent

Thomas, there is a question for you in the second commit: would you
care to explain what your goal was when you added --hard-dereference
when extracting the Blackfin toolchains?

Regards,
Yann E. MORIN.
