is of course a sequence of events. What I do know for sure is that YP will
build Qemu without video support if libsdl-devel is missing on your host
system because that happened to me before. You will not notice it unless
you go back to the log of the configure task and check the output.

Removing sstate triggered a rebuilt of qemu-native which also includes
running the configure task again whose output sets the switch whether or
not Qemu is built with video support. Apparently the first time you built
it it could not find libsdl-devel on your host but the second time it
could. But of course I cannot tell you why that happened. Do you still have
the logs? Did you install libsdl-devel between the two attempts?
