[Buildroot] [PATCH 01/11] toolchain-external: apply kernel headers check to non-custom toolchains

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

Thomas, All,

On 2014-06-01 12:47 +0200, Thomas Petazzoni spake thusly:
> Since the introduction of the kernel headers Config.in options, the
> external toolchain logic had a check for custom external toolchains to
> verify that the kernel headers version entered by the user matches the
> one of the toolchain. However, this check was not made for non-custom
> external toolchains (i.e the built-in profiles, such as Linaro,
> CodeSourcery and al.), making the assumption that the Buildroot
> developers will do the right selection.
> 
> However, it is quite nice when bumping external toolchains to have
> this automatic kernel headers version check, to ensure we select the
> appropriate kernel headers version.
> 
> Therefore, this commit makes the kernel headers version check
> applicable to non-custom external toolchains.
