They aren't required, just one more stupid config option.

And while we're at it, data from my usual config adding _NS options
one-by-one.

$ size vmlinux-000 vmlinux-uts-ns vmlinux-ipc-ns vmlinux-user-ns vmlinux-pid-ns
text data bss dec hex filename
2560804 217296 225280 3003380 2dd3f4 vmlinux-000
2560948 217296 225280 3003524 2dd484 vmlinux-uts-ns (+144)
2561452 217296 225280 3004028 2dd67c vmlinux-ipc-ns (+504)
2561805 217296 225280 3004381 2dd7dd vmlinux-user-ns (+353)
2562819 217300 225280 3005399 2ddbd7 vmlinux-pid-ns (+1018)

What amazing .text savings we have here.
