For some reason undefined symbols were downgraded to warnings, which means building a firmware that calls missing functions (= address zero) was perfectly fine, which of course made development more exciting.... This applies to builtins, too, printf of one char gets downgraded to putchar, which we don't have, so disable builtins. Change-Id: I492f41ad4162b9d07b1881ae4aed019db2dff8b5
