Subject: [PATCH] set_my_tls_end_of_input: Use an arbitrary but valid pointer
 as value

Pass a valid pointer to pthread_setspecific to avoid GCC 11 warning.
Fixes

src/tbb/tls.h:44:46: error: 'int pthread_setspecific(pthread_key_t, const void*)' expecting 1 byte in a region of size 0 [-Werror=stringop-overread]
|    44 |     void set( T value ) { pthread_setspecific(my_key, (void*)value); }
|       |                           ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
| compilation terminated due to -Wfatal-errors.
