5. Do what I've done for neard, i.e
package/neard/neard-fix-missing-linux-nfc-header.patch: we add a
patch to the package that integrates directly into the package the
required kernel headers, and adjust the autoconf script to either use
the header from the toolchain if it's available, or the bundled header
if not. Over time, toolchains will be updated to more recent kernel
header versions, and we should be able to get rid of such patches.

Even though it's not really nice, I believe it's the least painful way.

Of course, it has the drawback that if the user happens to use a kernel
version that does not have the NFC functionality of the media-ctl
functionality, it will simply not work.

Best regards,

Thomas
