This error means that you have a relocation which uses a 16 bit field
to refer to a global offset table entry, and that the address of the
table entry does not fit into 16 bits.

Probably it's because you are using -oformat.  That often doesn't work
in the presence of PIC relocations.  Instead of using that, generate
an ELF file, and use objcopy to change to the format you want.

Note that R_68K_GOT16O implies that you are linking code compiled with
-fpic.  Such code requires a dynamic loader at run time.  It's
unlikely that converting it to binary will make any sense.
