dwz testsuite fails with:
[   57s] FAIL:

which can be easily reproduced with:
$ g++ ./testsuite/dwz.tests/odr.cc ./testsuite/dwz.tests/odr-2.cc -DKIND=struct
-g -o 1
$ cp 1 2
$ dwz --odr 1 2 -m 3
$ readelf --string-dump=.gnu_debugaltlink 1

String dump of section '.gnu_debugaltlink':
  [     0]  3
.......
readelf: Warning: Section '.gnu_debugaltlink' in linked file '3' was not dumped
because it does not exist

while before the revision, there was no such a warning.
