This failure happens while building drivers/scsi/mpi3mr/mpi3mr_fw.o.

How to check:

    make ARCH=m68k drivers/scsi/mpi3mr/mpi3mr_fw.s
    make ARCH=m68k V=1 drivers/scsi/mpi3mr/mpi3mr_fw.o

Run the output from the last command with mpi3mr_fw.c by mpi3mr_fw.s,
so you will get sensible line numbers:

    drivers/scsi/mpi3mr/mpi3mr_fw.s: Assembler messages:
    drivers/scsi/mpi3mr/mpi3mr_fw.s:1849: Error: value -168 out of range
    drivers/scsi/mpi3mr/mpi3mr_fw.s:1849: Error: value of -168 too
large for field of 1 byte at 3175

Note that the value differs, but I'm using a different compiler
(gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04)).

The offending instruction is:

    | drivers/scsi/mpi3mr/mpi3mr_fw.c:299:  switch (host_tag) {
            mvz.w %d2,%d0   | tmp160, host_tag
            mov3q.l #5,%d1  |,
            cmp.l %d0,%d1   | host_tag,
            jcs .L154               |
            tst.w %d6       | host_tag
            jeq .L133               |
            subq.l #2,%d2   |, tmp238
            mvz.w %d2,%d2   | tmp238, tmp240
            mov3q.l #3,%d0  |,
            cmp.l %d2,%d0   | tmp240,
            jcs .L140               |
            add.l %d2,%d2   | tmp244
>>>         move.w .L155(%pc,%d2.l),%d0     |, tmp245
            jra .L186               |

And the table L155 is just too far from the above instruction, so
the displacement is too large, causing the failure.

Looks like a compiler bug to me?

Yes, it's https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104028.

Thanks for the information, we have added the commit 43ca110050
