Proposed patch

Well if the spec says that they are not allowed then that does make things
easier.

How about this revised patch ?  It makes the assembler issue an error message
if the user tries to assemble a file containing DWO sections that need
relocations, and it makes objcopy complain if it is asked to extract the dwo
sections of a file which has relocations against those sections.

Cheers
  Nick
