That's true, we don't want to keep sections referenced by debug
sections. It's also the case that adding a default
gc_mark_extra_sections really only benefits us if we want to implement
dropping notes and other special sections when all other sections in a
file are garbage collected. So for the time being I guess your patch
is OK if you remove the SHT_NOTE test in elf_gc_sweep. Please also
verify that your testcase behaves on Nick's large set of targets
