I have a different picture here. If you look at the logs at
https://kerneltests.org/builders/qemu-xtensa-master/
there's a line for noMMU config in every one of them:
Building xtensa:de212:kc705-nommu:nommu_kc705_defconfig ... running
............ passed
Please let me know if you observe any specific build/runtime issues.
This is what I get:
$ make ARCH=xtensa O=build/xtensa nommu_kc705_defconfig vmlinux V=1
....

I think there were other errors in the past, but every time I tried
it, the build failed for me.
