nptl: Fix pthread_create.c build with clang
clang complains that libc_hidden_data_def (__nptl_threads_events)
creates an invalid alias:
pthread_create.c:50:1: error: alias must point to a defined variable or function
libc_hidden_data_def (__nptl_threads_events)
^
../include/libc-symbols.h:621:37: note: expanded from macro
'libc_hidden_data_def'
It seems that clang requires that a proper prototype is defined prior
the hidden alias creation.
