			The hexloader test invokes QEMU with the -nographic argument. This is unnecessary, because the qtest_initf() function will pass it -display none, which suffices to disable the graphical window. It also means that the QEMU process will make the stdin/stdout O_NONBLOCK. Since O_NONBLOCK is not per-file descriptor but per "file description", this non-blocking behaviour is then shared with any other process that's using the stdin/stdout of the 'make check' run, including make itself. This can result in make falling over with "make: write error: stdout" because it got an unexpected EINTR trying to write output messages to the terminal. This is particularly noticable if running 'make check' in a loop with while make check; do true; done (It does not affect single make check runs so much because the shell will remove the O_NONBLOCK status before it reads the terminal for interactive input.) Remove the unwanted -nographic argument.
