qemu-timer: Check for usable fields for SIGEV_THREAD_ID
Older glibc (RHEL 5.x, Debian 5.x) does not have the _sigev_un._tid member in its structure definition, while the accompanying kernel headers do define SIGEV_THREAD_ID. We need configure to check for both before using it. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
