	ECR #333753 - linker: rely on builtins library triple instead of elf binary

	This is the first of multiple changes aimed at unifying the
	offline linker (llvm-link) with the online linker in the compiler
	library. The online linker is considered state-of-the-art and the
	code there needs to be made available to the offline linker.

	This change teaches the online linker to determine the target by
	examining the target triple on the builtins library modules,
	instead of checking the elf binary target. The assumption is that
	the builtins library always matches the actual target as
	confirmed in CL 1041226. This removes one dependence of compiler
	library functions so that the affected code can eventually be
	moved to llvm/lib and shared with the offline linker.

	The change passes smoke_clang (Orca build), smoke (HSA build) and Teamcity pre-checkin.
