[Xen-devel] [PATCH] mini-os: build fixes for lwip 1.3.2

[David Vrabel <david.vrabel@xxxxxxxxxx>]

From: David Vrabel <david.vrabel@xxxxxxxxxx>

Various fixes to mini-os needed to build lwip 1.3.2:

- Don't build the tests.
- Endianness macros #defined in arch/cc.h.
- free() is called via a function pointer so it needs to be a real
  function.
