You missed Jakub's request to factor out SPECS_DIR:

Maybe factor out:

SPECS_DIR := ../../../../Documentation/netlink/specs

? It's pretty long and we repeat it all over the place.

Did you miss Jakub's review comment: TOOL2 -> TOOL_RST ?

Also Jakub's comment:

No strong preference but I'd count .rst as final artifacts so I'd clean
them up in distclean target only, not the clean target. The distinction
itself may be a local custom..
