Not really.  Your easiest bet is to just use the C++ compiler driver to
link the test application.

In case you are using Automake, you can force the C++ linker for
otherwise C code with something like
  if FALSE
  nodist_prog_SOURCES += dummy.cpp
  endif

or, more generally, by overriding prog_LINK or LINK.

Cheers,
