I think you are confusing "runtime library" and "dynamic library".

No, that's entirely incorrect.

The runtime exception doesn't distinguish between static linking and
dynamic linking, and neither does the runtime exception, as clearly
stated in its FAQ:
"neither the GPL nor the GCC Runtime Library Exception distinguish
between static linking, dynamic linking, and other methods for
combining code in their conditions. The same permissions are available
to you, under the same terms, no matter which method you use."
