I see, you do want to rebuild everything, but only once. I have a script
that I use to rebuild everything only once, you could modify it to use
your list of files.
#!/bin/bash
EMERGE_ARGS="--oneshot --keep-going"
usage() {
echo -e "\nUsage: $(basename $0) [-f file] [-r
category/package[-version] [-h]"
echo " -f re-emerge all packages older than this file"
echo " -r re-emerge all packages older than this package"
echo " -h Show this text"
echo -e "\n All other options are passed to the emerge command"
echo -e "$*"
exit
}

case "${ARG}" in
