Thanks for this contribution! Looks mostly good. However, one important
thing that is missing is your Signed-off-by in the commit log. Could
you resend with this added ?

You need a Config.in comment here:

comment "flatbuffers needs a toolchain w/ C++, gcc >= 4.7"
	depends on !BR2_INSTALL_LIBSTDCPP || !BR2_TOOLCHAIN_GCC_AT_LEAST_4_7

Using OFF and TRUE doesn't look very consistent. Can we use OFF/ON
instead ?
