binutils 2.17 warns m68k:cpu32 is incompatible with m68k:cpu32

(I'm not subscribed, so I would appreciate CC's, but I'll watch the
archives anyways just in case.)

When trying to link two or more cpu32 object files with ld from binutils
2.17, I get a warning that the m68k:cpu32 architecture of any input
files beyond the first is incompatible with m68k:cpu32 output, which
seems very nonsensical.

Should I be concerned with these warnings?  ld from binutils 2.15 and
2.16.1 do not give this warning.  I found a somewhat similar report in
the archive from about a week and a half ago[1], but this seems to 
differ enough to be a different problem.  (Also, no one appears to have 
replied to it yet.)

To reproduce, configure binutils 2.17 with --target=m68k-elf, install,
and proceed as follows:

$ m68k-elf-as -mcpu32 -o start.o << EOF
.globl _start
_start:
jbsr foo
jbra _start
EOF
$ m68k-elf-as -mcpu32 -o foo.o << EOF
.globl foo
foo:
rts
EOF
$ m68k-elf-ld start.o foo.o
m68k-elf-ld: warning: m68k:cpu32 architecture of input file `foo.o' is
incompatible with m68k:cpu32 output

Thanks.
