zeroing which section when? Or how else could I narrow the problem
down?

The reloc info for 'optind' looks like that:
# m68k-linux-readelf -r /usr/m68kroot/objdump  (the faulting program)

Relocation section '.rela.dyn' at offset 0x161c contains 15 entries:
 Offset     Info    Type            Sym.Value  Sym. Name + Addend
.......
800367ac  00007613 R_68K_COPY        800367ac   optarg + 0
800367b0  00008013 R_68K_COPY        800367b0   optind + 0


# m68k-linux-readelf -r /usr/m68kroot/libc-2.2.90.so
Relocation section '.rela.dyn' at offset 0x11228 contains 3181 entries:
 Offset     Info    Type            Sym.Value  Sym. Name + Addend
.......
