sys-kernel/rt-sources does not auto-create the /usr/src/linux symlink. I have noticed this on multiple machines for quite some time now. I have always had to manually ln -s the symlink after emerging rt-sources.
Ebuild is missing kernel-2_pkg_postinst call. Adding this should fix symlink creation.
Thank you for the report and your solution. Could you please attach your solution as patch to the ticket? (.diff)
