jfyi. Downstreams started to remove it with hacks

	# Remove "limit memory usage" flags, it's already verified by
	# CHECKREQS_MEMORY and causes unneccessary errors. Upstream set them
	# according to CI OOM failures, which are not applicable to normal Gentoo build.
	sed -i -e '/\.max_rss = .*,/d' build.zig || die
