Well, that is an issue. An application that builds with 1.6 may not
build with 1.4, so they are not compatible API-wise, and therefore
having libgpiod.mk fall back to 1.4 automatically when the kernel
headers are too old is going to potentially break applications that use
1.6-specific APIs.

That is fine.
