Given that you are still linking in ctr0.o and libc, it's not surprising
that it's huge. I'd suggest the following steps... Rename main() to start().
Compile the C to assembly (-S option to gcc). Edit the assembly file to
remove all the unnecessary stuff. Assemble the file using "as". Link the
object using "ld".
