configure: Handle having no c++ compiler in FORTIFY_SOURCE check 



Our FORTIFY_SOURCE check assumes that $cxx refers to a working C++
compiler, with the result that if you don't happen to have one
then configure will spuriously print
  configure: line 4685: c++: command not found

Fix this by adding a 'has $cxx' check.
