Newer versions of binutils allow ar to be compiled to generate "deterministic archives" by default: in this mode no timestamp information is generated in the static archive, which utterly breaks GNU make's archive updating capability. Debian and Ubuntu have turned this feature on by default in their distributions which causes the regression tests to fail. Update the regression tests to check for the availability of the "U" option to ar which disables deterministic archives and allows GNU make's archive support to work properly again.
