I don't believe either is true. Passing it unconditionally wouldn't be
a good plan, as it breaks some cases (as I mentioned above).
Are you perhaps thinking of "-Wl,-z,relro" (which is related to
hardening)?

Aha, this part is interesting (and suggests that "-Wl,--as-needed" will
fix this, if it doesn't break anything; and if not, sorting out the -l
flags passed should resolve it):
