I don't know what weird system you're running over there, but here's
the situation on mine:
blake$ ls -li /usr/bin/{nm,objformat}
55853 -r-xr-xr-x 9 bin bin 4420 Sep 4 16:36 /usr/bin/nm
55853 -r-xr-xr-x 9 bin bin 4420 Sep 4 16:36 /usr/bin/objformat
blake$ ls -l /usr/libexec/{aout,elf}/nm
-r-xr-xr-x 1 bin bin 9168 Sep 4 16:36 /usr/libexec/aout/nm
-r-xr-xr-x 1 bin bin 157560 Sep 4 16:32 /usr/libexec/elf/nm
In other words, your proposal was implemented long ago. Take a look
at the sources for "objformat".
