Actually I am not sure it is not needed. Seems like purpose of this
exporter was the same as for static libraries in a non-static build -
not to allow to remove any public symbols of these libraries.

Because linker can eliminate some parts of static libraries, if sees
they are not used in the final executable.

So probably EXPORT_LIST for static build should be exported just like
exports.h, and it was missed in #2971.

Have you tried static build or normal build? Did you see the content
of EXPORT_LIST, what is there? Isn't this related to
