Depends of the country, a lot of countries have exceptions for interoperability (at least the whole EU) and since these projects are mainly used to make ports to other systems, it may be covered.
This is an absolutely ridiculous interpretation. There is no interoperability here at all, you are literally just copying the work in question.
It is like claiming that compiling Samba to run in $NEW_PLATFORM suddenly strips Samba of the GPLv3.
