If Martin is using the external toolchain backend, then he cannot check
anything related to the kernel headers version in the menuconfig.
External toolchains are pre-built toolchains, so Buildroot just uses
them as-is, you have no way of changing the Buildroot version.

Martin: your external toolchain is using too old kernel headers to
build udev. So your options are:

 *) Use a more recent external toolchain that will have more recent
    kernel headers.

 *) Add a patch to udev that defines BTN_TRIGGER_HAPPY to the correct
    value when it is not already defined by kernel headers.

BTW, which external toolchain are you using?

Thanks,

Thomas
