This does - without any doubt - allow porting GPL to non-free Operating Systems. We all should keep in mind that GPL Version 2 was written 1991. At this time using an free OS really was not common - linux was in its very early stages far from beeing an reliable OS. Free software at this time had to be linked to non-free operating systems.
