Subject: [PATCH v2 0/3] nolibc: Add fread() and fseek()

v1 blurb:

Using nolibc on nommu 68000, something I'm trying to build[0] wanted fread() and fseek()
so I added them, they seem to work so I'm sharing them. Not sure if I need to add
tests or something? Maybe there is a reason these weren't implemented in the first place...

Changelog:
v2:
- A few style clean ups in fread() requested by Thomas.
- Added a basic test that exercises the new functions. This isn't a complete POSIX
  testsuite, just a very basic smoke test. I couldn't think of proper error numbers
  for different failure cases (Suggested by Thomas), any ideas appreciated.

Daniel Palmer (3):
  tools/nolibc: Add fread() to stdio.h
  tools/nolibc: Add fseek() to stdio.h
  tools/nolibc: Add a simple test for writing to a FILE and reading it
    back
