Comment (by kencu):

 Oh, OK, you had noted `${prefix}/bin/as`
 [https://trac.macports.org/ticket/37846#comment:15 above].

 Turns out `/usr/bin/as` is even worse on older systems, as it is just an
 even older version of cctools, although may well provide the exact same
 assembler:
 {{{
 $ /usr/bin/as -version
 Apple Inc version cctools-809~2, GNU assembler version 1.38
 }}}

 Good to know there are different ways of doing things.

 You have me thinking now. I'd like to somehow prove that `-Wa,-q` actually
 calls through to `clang` instead of `/usr/bin/as` or `${prefix}/bin/as`
 just so I know for sure what I'm saying is actually fully correct. I'll
 see if I can figure out how to do that. -- K
