[Buildroot] [PATCH] qemu: Update defconfigs to Linux 4.19.16

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

Hello Gerome,

Thanks a lot for working on this, it's very useful to have our qemu
defconfigs regularly updated and tested!

Word missing at the beginning: "riscv *defconfigs* are left"

Also, please wrap the lines of the commit log to 72 characters.

Actually, maybe it would make sense for those qemu defconfigs to be
runtime tested as part of the .gitlab-ci.yml that is in Buildroot
itself ?

This would probably require extending:

.defconfig_script:
    script:
        - echo 'Configure Buildroot'
        - make ${CI_JOB_NAME}
        - echo 'Build buildroot'
        - |
            make > >(tee build.log |grep '>>>') 2>&1 || {
                echo 'Failed build last output'
                tail -200 build.log
                exit 1
            }

with some additional commands to see if it is a qemu defconfig, and if
it is, run it under Qemu.
