Subject: [Buildroot] [PATCH v8 07/14] toolchain: add post-install hooks making the toolchain relocatable
Date: Sun, 17 Apr 2016 23:38:24 +0200	[thread overview]
Message-ID: <1460929111-15615-8-git-send-email-s.martin49@gmail.com> (raw)
In-Reply-To: <1460929111-15615-1-git-send-email-s.martin49@gmail.com>

This change adds the required dependency and post-target-install hooks
to render the toolchain relocatable.

Notes:
- Although the toolchain package is a virtual package, it does support
  hooks.
- This has to be post-target-install hooks because the toolchain package
  is handled as a "target" package.

Ultimately, this patch allows to generate relocatable toolchains, just
by doing:

  $ make menuconfig
  $ make toolchain

Then, this toolchain can be used/shared/deployed anywhere*.

*: on any Linux system with an ABI-compatible set of system libraries
   (usually including: glibc, libgcc, zlib, flex and libsigsegv).
