+qemu-riscv32: Syscall LSEEK returns -14 (EFAULT)
+Description of problem:
+The lseek() system call returns -14 (EFAULT) if the file descriptor is correct,
+which it should never do (According to the lseek(2) man page).
+
+Here is some demonstrative code:
+```
+/* System Call numbers, according to https://github.com/riscv-software-src/riscv-pk/blob/master/pk/syscall.h */
+.set SYS_OPENAT,  0x38
+.set SYS_CLOSE,   0x39
+.set SYS_LSEEK,   0x3e
+.set SYS_READ,    0x3f
+.set SYS_WRITE,   0x40
+.set SYS_EXIT,    0x5d
+
+.set SEEK_CUR,    1
+
+/* According to https://elixir.bootlin.com/linux/v5.16.2/C/ident/AT_FDCWD */
+.set AT_FDCWD,    (-100)
+
+.section .text
+.global _start
+_start:
+
+/* Open the file with SYS_OPENAT, because SYS_OPEN does not exist on riscv32 for some reason.
+   Effectively:
+   s0 = open(argv[1], 0, 0644); */
+li a7, SYS_OPENAT
+li a0, AT_FDCWD
+lw a1, 8(sp)
+li a2, 0
+li a3, 0644
+ecall
+
+/* Error checking. This succeeds. */
+blt a0, zero, unrelated_error
+
+mv s0, a0
+
+/* The broken lseek() call.
+   Same also happens no matter the position in the file.
+   Effectively:
+   lseek(s0, 0, SEEK_CUR); */
+li a7, SYS_LSEEK
+mv a0, s0
+li a1, 0
+li a2, SEEK_CUR
+ecall
+
+/* XXX: lseek() returns -14 */
+blt a0, zero, lseek_error
+
+/* Close the file. */
+li a7, SYS_CLOSE
+mv a0, s0
+ecall
+
+/* Error checking. This also succeeds. */
+blt a0, zero, unrelated_error
+
+/* exit(0); */
+li a7, SYS_EXIT
+li a0, 0
+ecall
+
+/* exit(-return_value); */
+lseek_error:
+li a7, SYS_EXIT
+sub a0, zero, a0
+ecall
+
+unrelated_error:
+li a7, SYS_EXIT
+li a0, 128

+```
+Steps to reproduce:
+1. riscv32-unknown-linux-gnu-as test.s -o test.o
+2. riscv32-unknown-linux-gnu-ld test.o
+3. qemu-riscv32 ./a.out test
+4. echo $? # This returns 14
