So, the problem is objcopy can't covert 64bit SPARC/ELF to 32bit SPARC/a.out.
Could you post the working 32bit kernel linker script?

The odd thing is vmlinux is 64bit and sun4 32bit. Does objcopy work with
32bit vmlinux?

I understand objcopy won't work and I am not sure if there is
anything we can do with objcopy. The best hope is to make the
linke to generate kernel in a.out from the ELF .o files. To check
it out, I need
