kas subdirectory:  adb/{OS version}/{machine type}

Each different machine architecture has unique libraries and macros specifically
tailored for that version.  You need to create a directory hierarchy for each
CPU type you have which is running the given version of the OS.

Appropriate subdirectories would be:

	sun4
	sun4c
	sun4m
	sun4d


This information can be obtained on each system by `/usr/ucb/arch -k` (4.x)
or by `uname -m`.
