Нет, это не флаг

emerge -pv squid дает на выходе

[ebuild N ] net-proxy/squid-2.6.17 USE="pam samba ssl (-ipf-transparent) -ldap -logrotate -nis (-pf-transparent) -qos -sasl (-selinux) -snmp -zero-penalty-hit" 1,685 kB

А вот ACCEPT_KEYWORDS=~x86 emerge -pv squid дает

[ebuild N ] net-proxy/squid-3.0.1 USE="pam samba ssl -icap-client (-ipf-transparent) -ldap -logrotate -nis (-pf-transparent) -radius -sasl (-selinux) -snmp" 2,351 kB

Так что сей флаг появляется в более поздних версиях.

С наилучшими пожеланиями,
