Fix pthread_setname_np detection on Linux and snprintf usage warning
(fix of commit ab91e4e84)
Issue #300 (bdwgc).
* configure.ac [$THREADS==posix]: Replace AC_TRY_LINK with
AC_TRY_COMPILE to detect pthread_setname_np presence and kind.
* pthread_support.c [PARALLEL_MARK && (HAVE_PTHREAD_SETNAME_NP_WITH_TID
|| HAVE_PTHREAD_SETNAME_NP_WITHOUT_TID)] (set_marker_thread_name):
Replace snprintf() with BCOPY() call and manual conversion of an
integer (with 1-2 digits) to a string; remove undef name_buf.
* win32_threads.c [PARALLEL_MARK && HAVE_PTHREAD_SETNAME_NP_WITH_TID]
(set_marker_thread_name): Likewise.
