Driver: Claim -arch options when pipelining, and claim arguments that

are forwarded to GCC.
 - The later is unfortunate, as it prevents us from generally warning
   about anything interesting on platforms that use a generic
   toolchain. However, we can't do much better without significantly
   complicating things, and generally we should have proper tool chain
   definitions.
