[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=78d4e60c0e534dd3f1141cc2585fa5ef21ef0720
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

Using a variable in a printf format string may lead to undesirable
results if the variable contains format controls, so replace

    printf "foo $var bar"

by

    printf "foo %s bar" "$var"
