jb 2e1938f076 Make a couple of the stat flags dependent on the sys/stat.h header file
that this source is compiled against. This source is referenced by
install which is needed as a build tool and must be able to compile
against NetBSD headers and libraries if we have a hope of supporting
another architecture.

With this change, that's two working programs down and 3945 (?) to go.
The other one was make, but that didn't need any changes to work under
FreeBSD/Alpha. 8-)
