The test constantly fails on my Intel hybrid machine. The issue was it
has two events in the output even if I only gave it one event.
$ perf stat -e instructions -- perf test -w sqrtloop

Let's modify the awk script to add the values for each line and print
the total. The variable 'i' has a number of input lines that have valid
output and variable 'c' has the sum of actual counter values. That way
it should work on any platforms.
