This is the wrong fix.  Distutils is dumber than you think.  This patch 
just breaks C++ compilation in a different way.  The correct solution 
is a patch to distutils of some kind.

from distutils/unixccompiler.py:174

                 if target_lang == "c++" and self.compiler_cxx:
                     linker[0] = self.compiler_cxx[0]
                 self.spawn(linker + ld_args)

"linker" is the variable expanded LDSHARED (or whatever comes out of 
sysconfig.customize_compiler).
