Okay, checking cvsweb (which I should have done earlier), I note that this
was changed in rev 1.3 of basesrc/lib/libarch/m68k/m68k_sync_icache.S,
with a comment about a missing '#' character, and it having been useless
for more than a year.

It _should_ have been writing the immediate value, but it was going for
the absolute address instead.

The fix appears to be in 1.4.3 and 1.5, which means I need to replace my
libm68k...
