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

[Alexander Kapshuk <alexander.kapshuk@gmail.com>]

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.
