[Buildroot] [git commit] linux-headers: allow specifying 4.8 as kernel header version

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=d3ac2bc616803b40efad1e620ffe09eb7f7d1565
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Even though 4.8 is not released yet, some people may want to build a
system using the 4.8-rc kernel, and point to the kernel sources as the
kernel headers to use for the toolchain.

In order to make this possible, this commit adds support for specifying
4.8 as the kernel headers version, in both the internal and external
toolchain logic.
