No, it implies that a built binary requires a kernel at least as new as the
.h files used when building.  This is NetBSD (and SysV and ...) standard
practice, and is the foundation of how autoconf tests work.

The common practice of Linux users shuffling back and forth on kernel
versions is a glaring exception to this common-sense rule.  8-)
