CI fails when JSON is not activated, see:

https://source.denx.de/swupdate/swupdate/-/jobs/340677

I will suggest that swupdate-gethawkbitstatus won't be compiled if JSON 
was not turned on, something like in tools/MAkefile:

lib-$(CONFIG_JSON) += swupdate-gethawkbitstatus.o

Best regartds,
Stefano Babic
