Changes v1 -> v2 (after review of Thomas Petazzoni and reading of
https://patchwork.ozlabs.org/patch/814900):
 - Fix DEVELOPERS entry
 - Add dependencies on BR2_INSTALL_LIBSTDCPP and
 BR2_TOOLCHAIN_GCC_AT_LEAST_4_7
 - Set FLATBUFFERS_BUILD_SHAREDLIB depending on BR2_STATIC_LIBS instead
 of using BR2_SHARED_LIBS and BR2_SHARED_STATIC_LIBS
 - Add -DCMAKE_CXX_FLAGS="-std=c++11"
