Examples?
It will cause link failures because binutils now reports that it does
not have enough information to produce correct binaries.
This one from koschei:

I think it may be correct because libdwarf reference symbols in libelf
so should presumably link against it in order to get a NEEDED entry for
it in the ELF program headers.
None the less the man page for ld (at least on F27) says:
defs
Disallows undefined symbols in object files. Undefined symbols
in shared libraries are still allowed.
which says that undefined symbols are allowed when linking a shared
library even with -zdefs.
