+Subject: [PATCH] configure: Pass LDFLAGS to link tests
+
+LDFLAGS can contain critical flags without which linking wont succeed
+therefore ensure that all configure tests involving link time checks are
+using LDFLAGS on compiler commandline along with CFLAGS to ensure the
+tests perform correctly. Without this some tests may fail resulting in
+wrong confgure result, ending in miscompiling the package
+
+Upstream-Status: Submitted [https://github.com/madler/zlib/pull/599]
