This is safe (those places in the .o file are ignored in the final
link), but it may not give what the debugger expects.

For example, if the debugging info contained

    .4byte foo

and 'foo' is an external symbol, the relocation will have an addend of
0.  I don't know enough about DWARF to know if this can happen.
