-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.

-	PR dwz/27592
-	* testsuite/dwz.tests/odr-struct-multifile.sh: Call readelf with -wN
-	if supported.
-	* testsuite/dwz.tests/cycle.sh: Same.
