Hi,
Since binutils commit c46b706620e "Change the readelf and objdump programs so
that they will automatically follow links to separate debug info files" there
are a few FAILs in the dwz testsuite.
This is just due to changing the default behaviour for readelf.
Fix this by testing whether the new -Wn readelf flag is supported,
and if so, adding it to the readelf call.
Committed to trunk.
Thanks,
- Tom

* testsuite/dwz.tests/odr-struct-multifile.sh: Call readelf with -wN
if supported.
* testsuite/dwz.tests/cycle.sh: Same.
