[gcc-in-cxx] Pick up previous -lstdc++ in later bootstrap stages

[Ian Lance Taylor]

This patch adds support for picking up the -lstdc++ built in the
previous stage when doing a bootstrap.  This is done in $(CXX), in
$(CXX_FOR_BUILD), and by adding it to $(RPATH_ENVVAR) (normally
LD_LIBRARY_PATH).  Committed to gcc-in-cxx branch.

	* Makefile.tpl (POSTSTAGE1_HOST_EXPORTS): Add -L option to CXX and
	CXX_FOR_BUILD to pick up previous libstdc++.  Set RPATH_ENVVAR to
	point to previous libstdc++.
	* Makefile.in: Rebuild.
