Subject: readelf: Don't print 'for section' when rela section sh_info is zero.
X-Git-Tag: elfutils-0.160~22
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=eb4811dee133864ebbab1a062ac14af1f3ffdc62;p=thirdparty%2Felfutils.git

readelf: Don't print 'for section' when rela section sh_info is zero.

This matches how handle_relocs_rel already printed the header.
