From: Steven Rostedt (VMware) <rost...@goodmis.org>
commit 82a2f88458d70704be843961e10b5cef9a6e95d3 upstream.
The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.
Add 'tr "w" "W"' to merge the two and not worry about the ordering.
