Fix 'call to undeclared pthread_setname_np' errors in configure and cmake
Issue #474 (bdwgc).
Clang 15 makes implicit function declarations an error by default
which leads to configure (and cmake script) falsely thinking
pthread_setname_np symbol is not present.
* CMakeLists.txt [CMAKE_USE_PTHREADS_INIT] (check_c_source_compiles):
Always define _GNU_SOURCE before include pthread.h (regardless of
__CYGWIN__, __linux__, __GLIBC__, __GNU__ macros).
* configure.ac [$THREADS==posix] (AC_COMPILE_IFELSE): Likewise.
* include/private/gc_priv.h [!_GNU_SOURCE
&& (HAVE_PTHREAD_SETNAME_NP_WITHOUT_TID
|| HAVE_PTHREAD_SETNAME_NP_WITH_TID_AND_ARG
|| HAVE_PTHREAD_SETNAME_NP_WITH_TID)] (_GNU_SOURCE): Define.
