Everything is in the Buildroot Git repository, and besides that I
haven't heard of people working on i.MX6 "advanced" features. We have a
defconfig for the nitrogen6x board that was done by Peter, but I guess
Peter hasn't investigated the entire graphics stack of i.MX6 for now.
It would indeed be really, really great to improve i.MX6 support in
Buildroot (and also for other SoCs).

To me, it's the right solution. If you have userspace code that depends
on very specific kernel headers that are not part of a traditional
toolchain, then pointing to the kernel sources is the only solution.
Of course, it means that the package must "depends on BR2_LINUX_KERNEL"
and have <foobar>_DEPENDENCIES = linux.
