The kernel config is typically called "linux-<version>.config". In
your case, the version is gnublin_support_v1 which is a bit unfortunate,
so perhaps 3.7 is better.
(It would be nice if the gnublin kernel tree would tag with e.g.
It would also be nice if the gnublin kernel tree would contain a
defconfig for the board, then there's no need to include a custom linux
config in buildroot.
It would also be nice if it would follow the stable kernel (currently
3.7.6 I think).

Would be nice to mention the SoC used.

I guess that should be 3.7 (there is no 3.7.0 tag or tarball).

Tip: if you're not using conversions, cat is generally much more
efficient than dd:
cat output/images/u-boot.bin > /dev/sdc2
