specific version of a symbol. Definitions are primarily used to
ensure tests reference the exact compat symbol required, or define an
interposing symbol of the right version e.g. __malloc_initialize_hook
in mcheck-init.c. Use compat_symbol to define such a symbol within
the shared libraries that are built for users. */
