[Buildroot] [RFCv3 02/15] toolchain: post-pone evaluation of TOOLCHAIN_EXTERNAL_BIN

[Yann E. MORIN]

Thomas, All,

On 2017-12-01 21:53 +0100, Thomas Petazzoni spake thusly:
> The upcoming per-package SDK functionality is heavily based on the
> fact that HOST_DIR, STAGING_DIR and TARGET_DIR are evaluated during
> the configure/build/install steps of the packages. Therefore, any
> evaluation-during-assignment using := is going to cause problems, and
> need to be turned into evaluation-during-use using =.
> 
> This patch fix up one such instance in the external toolchain code.
> 
> This change is independent from the per-package SDK functionality, and
> could be applied separately.
