I haven't tried building 32-bit libraries on a native 64-bit x86-64 system
myself.  But the variable you'd want to set to add C++ compiler options is
called CXXFLAGS (as described in the GNU Make documentation).  You need to
have that set while running the configure script; after that it should be
incorporated in the generated makefiles.
