The symbol versioning tests mix C-visible symbols and linker-visible symbols in order to verify .symver behavior. This works for most people, but fail for targets that have a symbol prefix. So add a helper file with macros that expand gcc's __USER_LABEL_PREFIX__ as necessary and convert all .symver users over to it. Now that the tests are usable on prefixed targets, update the tests to take into account an optional leading underscore. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
