Maybe try CFLAGS and CXXFLAGS?
Here is a similar example.

Adding it to LIB_FUZZING_ENGINE is indeed too hacky.

then
# adds quadratic complexity custom mutator one random build out of 10
clang -fPIE -I. -c $SRC/quadfuzz/quadfuzz.c -o $SRC/quadfuzz/quadfuzz.o
export LIB_FUZZING_ENGINE="-fsanitize=fuzzer $SRC/quadfuzz/quadfuzz.o"
echo "Using quadfuzz"
fi

for branch in "${fuzz_branches[@]}"; do
#we did not put libhtp there before so that cifuzz does not remove it
cp -r libhtp suricata$branch/
