Thansk again. There should obviously have been a sanity check just before the
unit_length read.

libdw: Check there are any header bytes in str_offsets_base_off
We tried to read the str_offsets header length and only then checked
if there were any bytes left. Make sure to check there are at least 4
bytes for the initial unit length.
* libdw/libdwP.h (str_offsets_base_off): Check before initial
unit_length read.
