description:
Hack to get the "has ANSI C headers" check to pass on newer versions
of clang as bundled with Xcode.  If someone really cares about ensuring
NetBSD's host tools build on a system without <stdlib.h>, then I'm sure
that enterprising individual will also find a super #correct fix for this
specific problem.
