+- BNC#776058
+- Add new patch to prevent the go install tool trying to reinstall
+  std library packages that are dependencies of third party packages.
+- Using touch on the precompiled archives introdoces additional
+  problems with the go install tool. Instead, we simply don't mark
+  std library files as stale when a third party package is evaluated
+  for installation. The behaviour remains unchanged for the root
+  user and while it is inadvisable to manually reinstall standard
+  libraries using the openSUSE packages, we do not disallow it.
