That's odd, as "man(7)" says "All of the arguments will be printed next to each

It doesn't. There's no portable way to use scanf and printf on it. You can't
reliably convert it to intmax_t. It doesn't have the associated _MIN and _MAX

The generation of the library call for the MINLOC/MAXLOC intrinsic
mishandled the optional KIND argument and resulted in a bad
argument list passed to the library function. The fix is obvious.
Regtested on x86_64-pc-linux-gnu.
OK for master? As it technically wrong code, OK for backports?
