Cleanup the use of TARGET in toplevel and common make and build files
Common file target.mk now passes the TARGET value through config.sub for canonification. Toplevel Makefile now calls target.mk so it handles TARGET like all sub-makefiles. Build script otp_build no longer creates a target specific directory that a long time ago was used for target specific configure cache file.
