This patch is needed to support lseek for x32:

diff --git a/file.c b/file.c
index 58585f3..5f3b506 100644
--- a/file.c
+++ b/file.c
@@ -501,7 +501,7 @@ static const struct xlat whence[] = {
 	{ 0,		NULL		},
 };

-#if defined(LINUX_MIPSN32)
+#if defined(LINUX_MIPSN32) || defined(X32)
 int
 sys_lseek(struct tcb *tcp)
 {

Thanks.
