+Subject: [PATCH] linux-user: remove host stime() syscall
+
+stime() has been withdrawn from glibc
+(12cbde1dae6f "Use clock_settime to implement stime; withdraw stime.")
+
+Implement the target stime() syscall using host
+clock_settime(CLOCK_REALTIME, ...) as it is done internally in glibc.
+
+Tested qemu-ppc/x86_64 with:
+
+	#include <time.h>
+	#include <stdio.h>
+
+	int main(void)
+	{
+		time_t t;
+		int ret;
+
+		/* date -u -d"2019-11-12T15:11:00" "+%s" */
+		t = 1573571460;
+		ret = stime(&t);
+		printf("ret %d\n", ret);
+		return 0;
+	}
+
+        # date; ./stime; date
+        Tue Nov 12 14:18:32 UTC 2019
+        ret 0
+        Tue Nov 12 15:11:00 UTC 2019
