No, if arch isn't supported reading whatever counter returns 0. On the other hand
if architecture does not require extra setup (eg., x86-64) all works
automatically because Linux has consistent API for each supported arch.

Test will be skipped because event is set to 'NULL' by default. Supported
architectures override it with valid name.
