missing files/404 errors on zephyrproject.org (drupal) pages

[nashif]

Reported by David Kinder: Meta tags in the drupal content of zephyrproject.org are referencing files that don't exist and are generating (silent) 404 errors on every page load for the site:

    <link rel="apple-touch-icon" sizes="72x72" href="sites/all/themes/custom/zephyr_theme/images /apple-touch-icon-72x72.png">
    <link rel="mask-icon" href="sites/all/themes/custom/zephyr_theme/images/safari-pinned-tab.svg" color="<span>#</span>5bbad5">
