cookutils view cooklinux @ rev 1019

cook: add fix() to use '--as-needed' linker flag in compile_rules(); cookit(): make QA fail on empty vars / bad values; remove_already_packed(): fix bug when $PACKAGE not listed in $SPLIT and we use this function for the default set. lighttpd/index.cgi: sort orphans. modules/precheck: separate error message by empty lines.
