I changed in bfd that all SEC_DEBUGGING sections have SEC_ALLOC and
SEC_LOAD bits set. This works, but then when those binaries are
stripped, again a failure appears (I assume it has to do with the
relocations in debug sections). In fact by spec the section flags are
correct, but as GNU emits for debugging formats .secrel32 relocations,
this can work, because on relocation attempt those sections aren't
allocated and loaded. A general way to solve this would be to remove
those section relative relocations at all and do the relocation itself
based to the _image_base.
Cheers,
Kai
