This change is setting up for switching over to proper POSIX option requirements, feature test macros, and a dependency structure that is reflective of the standard. Signed-off-by: Christopher Friedt <cfriedt@meta.com>

|
When running several SMP applications in parallel instances of Qemu,
|
|
e.g. via twister, explicit serialization may be required between
|
|
pthread_create() and zephyr_thread_wrapper() when spawning and joining
|
|
many pthreads concurrently.
|
|
|
|
On such systems, say Y here to introduce explicit serialization
|
|
via pthread_barrier_wait().
