+Subject: [PATCH] [testsuite] Handle readelf following links by default
+
+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.
+
+2021-03-20  Tom de Vries  <tdevries@suse.de>
+
+	PR dwz/27592
+	* testsuite/dwz.tests/odr-struct-multifile.sh: Call readelf with -wN
+	if supported.
+	* testsuite/dwz.tests/cycle.sh: Same.
