package/python-matplotlib: needs a toolchain with C++ support

Browse Source 
Matplotlib contains .cpp source code:

ls src/*.cpp
src/_backend_agg.cpp
src/_backend_agg_wrapper.cpp
src/_contour.cpp
src/_contour_wrapper.cpp
src/ft2font.cpp
src/ft2font_wrapper.cpp
src/_image.cpp
src/_image_wrapper.cpp
src/mplutils.cpp
src/_path_wrapper.cpp
src/_png.cpp
src/py_converters.cpp
src/_tkagg.cpp
src/_ttconv.cpp
src/_windowing.cpp

So add a dependency on C++ support in the toolchain to fix build errors like
(no autobuilder reference yet):

../output/host/bin/powerpc-buildroot-linux-uclibc-gcc -Wno-unused-result \
  -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -D_LARGEFILE_SOURCE \
