[Buildroot] [PATCH v3 3/7] package/glibc: needs kernel headers >= 3.10 on powerpc64le

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

Romain, All,

On 2017-09-23 23:24 +0200, Romain Naour spake thusly:
> Since glibc 2.26, kernel headers >= 3.10 are needed on powerpc64le [1].
> In order to prepare the glibc bump to this version, we don't allow to
> build a Buildroot toolchain with kernel headers older than 3.10.

Ideally, this should have been part of the patch that does the bump to
2.26, but it is OK to have it just before to have smaller-to-review
patches.
