Sorry, I should have said: kernel-headers too old.

That toolchain is using headers from Linux 3.1.1, which are too old to
have the required defines (since they appeared in 3.3).

So, same issue, just a different phrasing.

Something like:

    config BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_1
        bool

    config BR2_TOOLCHAIN_EXTERNAL_LINARO_2013_11
        select BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_1

    config BR2_PACKAGE_DVB_APPS
        depends on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_1

And so on for all the headers version of interest?
