The relic slver is no longer used for individual versioning on functions and is confusing tools looking for data in text sections. This removes all instances instead of fixing since its usefulness is waining. Fixes #221 Change-Id: Ife0b9f105950a90337c58e8a41ac2cffc0f67d99 Signed-off-by: Greg Tucker <greg.b.tucker@intel.com>
