Hi,
In a lot of cases, we do not really care about the samples and histogram
files and their associated gnuplot command files or do not want to save them
for example on embedded platforms with limited or no storage.
This patch disables generating those files by default and introduce a new
parameter to the tests, namely '-s', for when we really want to.
Sebastien.
