So, this is a SCL of newer tools right?

Does this result in a runtime dependency? Or just a build time one?
ie, will everyone using packages built with this have to install it
also, or it's just a buildrequires?

It's a BuildRequires only because any newer features from the compiler are statically linked into the binary.
