Revert "ARC: build: retire old toggles"
This has caused a bunch of build failures at a few sites, with GNU 2015.12 and older as the assembler seems to need -mlock to be able to grok llock/scond instructions for ARC700 builds. different places since the older tools still seem to release of tools which most people are using seem to trip with the -mlock flag not being passed. This reverts commit c3005475889c7c730638f95d13be3360f0b33e98.
