Change 99475 by gabor at spitfire on 2006/06/17 22:57:24

	Add IA32_BINARY_PORT macro.  This is an enhancement for the existing
	NOT_FOR_ARCHS and ONLY_FOR_ARCHS system.  It should be set instead of
	the previous two knobs for ports that fetch and install compiled
	i386 binaries.  On ia64 and amd64 the kernel-level compatibility and the
	availability of the 32-bit libraries is checked and the port can only be
	installed if both succeeded.
	
	Also add SYSCTL variable for /sbin/sysctl. It makes the code easier to read.
	
	PR: ports/98105
