		<flag name="ipc">
			Use inter-process communication between Portage and running
			ebuilds.
		</flag>
		<flag name="native-extensions">
			Compiles native "C" extensions (speedups, instead of using
			Python backup code).  Currently includes libc-locales.  This
			should only be temporarily disabled for some bootstrapping
			operations.  Cross-compilation is not supported.
		</flag>
		<flag name="xattr">
			Preserve extended attributes (filesystem-stored metadata)
			when installing files. Usually only required for hardened
			systems.
