[Buildroot] [git commit] linux: don't take HEAD as default for git repositories

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=3a7a0a707be0f0a4b115990ce704a730b85ee3e4
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Specifying a floating tag like HEAD for a repository version is bad practice,
as it results in non-reproducible builds. This patch removes the default
assignment of HEAD as version when a custom git repository is used for the
Linux kernel.
