Its actually not that dangerous, given that ELF by default does this for any dynamic linking. However, it is possible to be more granular and specify the symbols which are okay to be undefined using the `-U <name>` option to the linker. It is slightly nicer than the blanket approach, but at a higher maintainence cost (any time the sanitizers change the hooks, it would need to be updated. But, that doesnt seem too bad.
