boards: native_sim: Workaround race condition in glibc

Explicitly link with libgcc_s to work around a race condition
in glibc when dynamically loading libgcc_s in multiple threads.

The race condition was observed when running native_sim with
CONFIG_REBOOT=y and CONFIG_NATIVE_SIM_REBOOT=y and rebooting quickly
from main().
