Well, the configure part of that is a joke.

objdump -T /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.16  | grep '\(__cxa_pure_virtual\|__si_class_type_info\)'
00000000000bdb10 g    DF .text  000000000000001f  CXXABI_1.3 __cxa_pure_virtual

So you could just do as I suggested and add -lstdc++ to the linker flags
(e.g. libs_mplayer="$libs_mplayer -lstdc++", though when writing a
proper configure check that should become quite obvious how to do it).
