FWIW I'm in favor.  -z is not uncommon in my experience.

That said, a principled way to handle this would be to forward exactly the set of flags that gcc documents:
https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#Link-Options

If you submit a patch to gcc to document -z as a linker option, then we can add it to clang and be done with it.  =D
