Comment (by noloader@…):

 This is probably related to `-Wa,-q`. When I originally tried to use it, I
 used it with a typo: `-Wa,q`. The typo resulted in:

 {{{
 $ /opt/local/bin/g++-mp-4.9 -Wa,q -c test.cxx
 as:file(q) Can't open source file for input! No such file or directory.
 }}}

 At that point, I thought the compiler did not support the option.

 Now that the typo has been corrected, it appears the option is supported:

 {{{
 $ /opt/local/bin/g++-mp-4.9 -Wa,-q -c test.cxx
 /opt/local/bin/as: assembler (/opt/local/bin/clang) not installed
 }}}
