Please keep the list in Cc, other Buildroot developers can give very
valuable insights, very often better than mine.

Is this a .config generated with the bare trunk, or with the trunk
modified to remove the two chunks that you mentionned previously ?
Since BR2_KERNEL_HEADERS_2_6_27 is set, I'm inclined to think that this
is a .config after removal of the two chunks.

The second option « same version as linux headers » clearly cannot work
with my patches: since we're using an external toolchain, there's no
version of linux headers defined in Buildroot.
So my proposal is:
1) remove the option "linux (same version as linux headers)" when an
external toolchain is used ;
2) improve the "advanced" support to suit your needs. What do you mean
by « I have to go in and update the values » ?
What do you think about this ?

Grant Likely recently sent a patch adding the ability to get the kernel
for a Git repository. See
This patch hasn't been integrated to Buildroot, yet.
