[Qemu-devel] [PATCH v3 4/6] tests/acceptance: Add test_mipsel_5kc_malta in BootLinuxConsole

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Similar to the test_x86_64_pc test, this boots a Linux kernel on a
Malta board (MIPS 5Kc little-endian) and verify the serial is working.

This test requires the dpkg-deb tool (apt/dnf install dpkg) to
extract the kernel from the Debian package.

  $ avocado run -p arch=mips64el tests/acceptance/boot_linux_console.py
