Hm, although it adds the "-x c++" to the xgcc command line, it
seems the C compiler is still used (I added some c++ specific code
to the test to check that).  At the moment I run

  $ make -k check-gcc RUNTESTFLAGS="s390-c++.exp=<testname>.c"

(Where s390-c++.exp is a copy of s390.exp that includes g++-dg.exp
instead of gcc-dg.exp, but I've no idea whether that is
sufficient.)
