There is no straightforward way to express that in an object file.

I'm not aware of any.  DWARF sections are normally at address zero.

If you are really only concerned about the .debug_frame section, you
should be looking instead at the .eh_frame section, which is loaded
into memory, and uses a slightly different format.  I don't know if it
will provide everything you need, though.

If you do need full debug info, then you'll have to tweak your DWARF
reader to adjust by the base of the debug sections as appropriate.
