Most likely, using "shell-command" will override it. Try using some
<arg> elements instead. The literal expansion is:

   <runner interface='http://repo.roscidus.com/utils/bash'>
     <arg>-c</arg>
     <arg>"$$@"</arg>
     <arg>-</arg>
   </runner>
   <arg>c++</arg>
   <arg>${SRCDIR}/test.cpp</arg>
   ...

(it's a bit ugly because you're searching for c++ in $PATH rather than
using a 0install interface, but in your case that may be what you
want)
