Well, the scan_dyntag_auxv routine I added already does
attempt to access PT_DYNAMIC if there is no .dynamic
section.  In fact, it should work even if you do not
have any executable file at all, as it directly reads
the program headers from the target.

Is there some reason why this doesn't work for you?
