Can you check if a
ifndef ($(BR2_PACKAGE_DIRECTFB),y)
	$(SED) "/directfb.h>/d" all/odd/files/*
endif

in the configure stage bypasses this odd dependency?
I.e. if we (or rather the SDL folks) don't need some structs from
directfb then we can wipe the header just fine.

Apart from that, isn't there a --disable-directfb or something like
that in SDL?
