OK but I think you can get this all to build with a little more as
follows:

Enable the cryptographic API (as built in rather than as module) with
CRC32c CRC algorithm, and iSCSI (under Device Drivers/SCSI device
support/SCSI low level drivers)

in your kernel configuration.

That should cause scsi_transport_iscsi (and iscsi_tcp) to be built which
should take care of the unresolved symbols you are seeing.
