There's a limited number of kernel versions supported for any buildroot
release, but as you are compiling your kernel seperately you are
completely free to choose your kernel version.

The kernel headers version doesn't have to be the same as the kernel
version (it only has to be new enough to provide headers for whatever
features you need).

You mean stuff on the build host? We do a dependency check when you run
make and error out if anything in missing.
