I think I made a mistake with qemu, It seems to partially work with these
instructions:
```
This is a configuration of testing the BUILD_KERNEL configuration.
$ cd nuttx
$ ./tools/configure.sh sabre-6quad:knsh
$ make V=1 -j7
$ make export V=1
$ cd ../apps
$ ./tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
$ make import V=1
$ cd ../nuttx
$ qemu-system-arm -semihosting -M sabrelite -m 1024 -smp 4 -nographic
-kernel ./nuttx
```
```
