program.ld: make sure that zeroptr isn't assigned to debug sections
Some ld versions seem to merge the .zeroptr section (NOLOAD, address 0) with some debug sections (NOLOAD, address 0) which makes the build explode when the debug sections are then stripped (including the zeroptr symbol). Just define zeroptr to be 0, no sections needed, to avoid this "optimization". Checked the objdump -dS of code using it that the accesses look sane.
