What microcode revision is that Xeon E5-2686 running?

We still need that instrumented libc if one is to test applications,
though, as most packages have little in the way of automated regression
test suites.  And people need to test the packages (using the
applications) with such an instrumented libc installed (or running on a
box with TSX active).
