Title:
  pwrite does not work right under qemu-sh4

Status in QEMU:
  New

Bug description:
  The pwrite system call has no effect when writing to a non-zero file
  position, in a program running under qemu-sh4 (version 2.9.0).

  How to reproduce:
  - Compile the program:
    sh4-linux-gnu-gcc-5 -O -Wall -static -o test-pwrite test-pwrite.c
  - Set environment variable for using qemu-sh4 (actually not needed, since the 
program is statically linked here).
  - ~/inst-qemu/2.9.0/bin/qemu-sh4 test-pwrite

  Expected output:
  buf = 01W3456789

  Actual output:
  buf = 0123456789
  test-pwrite.c:56: assertion 'strcmp ("01W3456789",buf) == 0' failed
  qemu: uncaught target signal 6 (Aborted) - core dumped
