From: Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx> Clang has an option "-meabi <arg>" which is used by the kernel for ARMv7. This kind of option, taking a argument without a separating '=', can't be ignored like most other options and must this be special-cased. So, add the special case for this option and consume the argument if it's one of the valid one.
