This broke generation of src.conf.5, which reports that WITHOUT_FDT is
the default after this change. Running `make makman` reports:
amd64/amd64: ignoring duplicate option FDT
arm/armv6: ignoring duplicate option FDT
...

Indeed, `make showconfig` shows MK_FDT is both yes and no:
$ make showconfig | grep FDT
MK_FDT           = no
MK_FDT           = yes
