>68k porters, could you try this with a recent binutils and report back
Not strictly speaking a porter, but… sure ☺
The example is pretty bad and won’t (can’t) compile, but
the problem still persists on latest (a-g d-u today!) sid:

The “info as” documentation doesn’t know .chip, and
even .chip 68020 (gcc’s default) makes assembling
fail.
And RTFM yields this:
root@ara5:~ # as -o x1.o x1.s
root@ara5:~ # objdump -dS x1.o
x1.o: file format elf32-m68k
Disassembly of section .text:

root@ara5:~ # cat x1.s
.cpu 68000

I don’t know whether .chip should do this, but if
you can, change (Emile?) to use .cpu instead or,
preferably, run it with -Wa,-m68000 or something
like that.

If Harry Potter gets a splitting headache in his scar
when he’s near Tom Riddle (aka Voldemort),
does Tom get pain in the arse when Harry is near him?
-- me, wondering why it’s not Jerry Potter………
