Similar to ppoll, the poll.h header needs to redirect the poll call to a proper fortified ppoll with 64 bit time_t support. The implementation is straightforward, just need to add a similar check as __poll_chk and call the 64 bit time_t ppoll version. The debug fortify tests are also extended to cover 64 bit time_t for affected ABIs. Unfortunately it requires an aditional symbol, which makes backport tricky. One possibility is to add a static inline version if compiler supports is and call abort instead of __chk_fail, so fortified version will call __poll64 in the end. Another possibility is to just remove the fortify support for _TIME_BITS=64. Checked on i686-linux-gnu.
