Subject: [PATCH 32/32] ver_linux: 'printversion()' function definition

Definition of the 'printversion()' function. The function tests whether
the variable that contains the version number is empty, and prints
the name of the utility and its version number as a formatted string,
if the version number is not an empty value.
