pru: Define multilib for different core variants
Enable multilib builds for contemporary PRU core versions (AM335x and
later), and older versions present in AM18xx.
gcc/ChangeLog:
* config.gcc: Include pru/t-multilib.
* config/pru/pru.h (MULTILIB_DEFAULTS): Define.
* config/pru/t-multilib: New file.
