Change 1198871 by brooks at brooks_vica on 2014/08/18 16:10:41

	Add a new variable LIBADD which itends to replace manual setting of
	DPADD and LDADD thus eliminating the possiblity of getting them out
	of sync, allowing easier transtions between libaries, and enabling
	more complex linking options such as whole program analysis via
	LLVM-IR.
