dtc does not support compiling overlays

[ptz]

I built Armbian_5.59_Nanopineocore2_Ubuntu_xenial_next_4.17.17.img for my board, and am trying to add an overlay dtb that describes a port expander I have on i2c2. 

$ sudo armbian-add-overlay ./mcp23008.dts 
Error: dtc does not support compiling overlays
Please try to install matching kernel headers

Getting a more recent version of dtc (1.4.7 instead of 1.4.0 which comes by default) solves the issue, but it'd be nice if this worked out of the box.
