+Byte-swapping issue in getresuid on qemu-user-sparc64
+Description of problem:
+When calling getresuid() in the big-endian sparc64 guest, the uid_t values are written with their 16-bit halves reversed.
+
+For example, the UID 0x000003e8 (1000) becomes 0x03e80000.
+Steps to reproduce:
+A minimal test case looks like this:
+```c
+#define _GNU_SOURCE
+#include <stdio.h>
+#include <sys/types.h>
+#include <pwd.h>
+#include <unistd.h>
+
+int main(int argc, char **argv) {
+	struct passwd *pw = getpwuid(geteuid());
+	if (pw == NULL) {
+		perror("getpwuid failure");
+		return 1;
+	}
+	printf("getpwuid()->pw_uid=0x%08x\n", pw->pw_uid);
+
+	uid_t ruid = 0, euid = 0, suid = 0;
+	if (getresuid(&ruid, &euid, &suid) != 0) {
+		perror("getresuid failure");
+		return 1;
+	}
+	printf("getresuid()->suid=0x%08x\n", suid);
+
+	return 0;
+}
+```
+
+Compile and run with:
+```
+$ sparc64-linux-gnu-gcc -Wall -O0 -g -o sid-sparc64/test test.c
+$ sudo chroot sid-sparc64
+[chroot] $ qemu-sparc64-static ./test
+```
+
+Alternatively, static compilation without a chroot is also possible (despite a warning about `getpwuid()`):
+```
+$ sparc64-linux-gnu-gcc -static -Wall -O0 -g -o test test.c
+$ qemu-sparc64-static ./test
+```
+
+Expected output:
+```
+$ ./test 
+getpwuid()->pw_uid=0x000003e8
+getresuid()->suid=0x000003e8
+```
+
+Actual output:
+```
+$ ./test 
+getpwuid()->pw_uid=0x000003e8
+getresuid()->suid=0x03e80000
+```
+Additional information:
+I'm not sure if this is a glibc, qemu or kernel issue, but it doesn't occur outside qemu.
