Seconded, and here are mine (the profile defaults may of course add a few
others):

(My make.conf simply includes one file. That way, if it gets overwritten,
it's very easy to fix. =8^) That file then serves as a master file,
simply including several other files, split out by functionality.)
$cat /etc/make.conf
source /etc/portage/make.conf/master
$cat /etc/portage/make.conf/master
source /etc/portage/make.conf/cflags
