[Buildroot] [PATCH 5/7] package/glibc: needs kernel headers >= 3.10 on powerpc64le

[Romain Naour <romain.naour@gmail.com>]

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.
