+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.

+%description
+The dwz package contains a program that attempts to optimize DWARF
+debugging information contained in ELF shared libraries and ELF executables
+for size, by replacing DWARF information representation with equivalent
+smaller representation where possible and by reducing the amount of
+duplication using techniques from DWARF standard appendix E - creating
+DW_TAG_partial_unit compilation units (CUs) for duplicated information
+and using DW_TAG_imported_unit to import it into each CU that needs it.
