These two options significantly increase the amount of stack space used by the logging thread as these generate both additional logging and generate deep stacks themselves. This fixes running the tests/subsys/logging/log_core_additional/logging.add.log1 test on riscv32 with THREAD_LOCAL_STORAGE enabled. Signed-off-by: Keith Packard <keithp@keithp.com>
