#5172: unix-compat does not build because of strangeness in GHC's header files.

---------------------------------+------------------------------------------
I have build 7.0.3 from source and then tried building unix-compat
library.
The library failed to build because it could not find libutil.h.
Digging a bit deeper I found the following:
unix-compat includes among other things header files from GHC.
./libraries/unix/include/HsUnixConfig.h has this in it:
/* Define to 1 if you have the <libutil.h> header file. */
#define HAVE_LIBUTIL_H 0
However, ./libraries/unix/include/HsUnix.h has this:
#ifdef HAVE_LIBUTIL_H
#include <libutil.h>
#endif
Naturally, it has tried to include the non-existing libutil.h. Even though
HAVE_LIBUTIL_H is zero, it is still considered to be defined.
After removing this line:
#define HAVE_LIBUTIL_H 0
unix-compat has been successfully built.
