Silence unused argument warnings from clang

The clang frontend ignores a number of options that are accepted by gcc
and llvm-gcc. However, it produces a warning for each unused argument at
each invocation, which can result in many lines of noise, e.g.

   clang: warning: argument unused during compilation: '-rdynamic'

Since these arguments do not affect compilation, let's just silence the
warnings by passing '-Qunused-arguments' to clang by default.
