Subject: bug#55846: make bootstrap -j2 fails on macOS
Date: Wed, 8 Jun 2022 12:52:04 +0200

I have no idea what the intention was, but it's slightly confusing that the originating commit (de3d0b572d) was ostensibly made to cope with make parallelism. (CC:ing the author, Jan Djärv, in case he still remembers anything.)

Just making one target depend on the other, as in the diff below, makes it work, but I'm not sure of the purpose of ns_check_file.
