[Buildroot] [git commit] linux/Config.in: clarify longterm 2.6 URL exception

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=a1ede0a51366a3418666f4cb1afd445fb969b967
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As this question has popped up multiple times on the mailing list, clarify
that selecting longterm 2.6 kernels requires the 'custom tarball' option
instead of 'custom version'.
