riscv discards .exit.* sections at run-time but doesn't define
RUNTIME_DISCARD_EXIT. However, the .exit.* sections are still allocated
and kept even if the generic DISCARDS would discard the sections due
to missing RUNTIME_DISCARD_EXIT, because the DISCARD sits at the end of
the linker script. Add the missing RUNTIME_DISCARD_EXIT define so that
it still works if we move DISCARD up or even at the beginning of the
linker script.

Thought I left one of these against v1, either way:
