I have also faced similar issue with libstdc++ try enabling garbage collector flags which will reduce the size up to some extent. ( Add -ffunction-sections -fdata-sections flags to your compiler flags and -Wl,--gc-sections to your linker flags ) or else use alternatives of iostream function i.e. instead of cout function use printf etc, try to avoid adding <iostream> library if you can..
