Comment (by raimue):

 On older systems, `/usr/bin/as` is an old cctools. That's why we started
 using `${prefix}/bin/as` from the cctools port instead, to get the
 benefits of the newer version.

 That's what I meant [comment:13 above]: we should only use `--with-
 as=/usr/bin/as` on newer systems on which `/usr/bin/as` is the newer LLVM
 assembler. On older systems leave everything as it is.

 Your theory on `-Wa,-q` is easy to prove:
 {{{
 $ /opt/local/bin/as -q
 /opt/local/bin/as: assembler (/opt/local/bin/clang) not installed
 }}}
