[Buildroot] [PATCH 0/5] Preparatory work on toolchains - v2

[Yann E. MORIN]

Hello All!

These are preparatory work on toolchain, laying ground to later add
crosstool-NG as a backend. Currently, these are rather an RFC, even
if it works OK for me.

Changes since v1:
- rebased against latest tree
- patches formatted to detect renames/copies

Yann E. MORIN (5):
    toolchain: move helper functions from external toolchain
    toolchain: rename external toolchain dir
    toolchain: move makefile includes
    toolchain: move buildroot config files
    toolchain: rename base target for external toolchains
