SC2086 is now reported for missing Double quote around
$FN since shellcheck 0.9.0:

In utils/config line 175:
                if grep -q "# ${BR2_PREFIX}$ARG is not set" $FN ; then
                                                            ^-^ SC2086 (info): Double quote to prevent globbing and word splitting.

In utils/config line 178:
                        if V="$(grep "^${BR2_PREFIX}$ARG=" $FN)"; then
                                                           ^-^ SC2086 (info): Double quote to prevent globbing and word splitting.
