The APIs in platform generally try not to raise errors, but instead
return a default value you pass in as parameter in case the
data cannot be fetched from the system.
The returned value should be a version string in a fixed
format, not a tuple. I'd suggest to use _norm_version()
for this.
Please also check whether this works on a few Linux systems.
I've checked it on openSUSE, Ubuntu.
