hash.c and _stat variants

[Joel Sherrill]

Hi Corinna,

I was going through my newlib patches and found where
I had undone your change and used the version without
the _.

        * libc/search/hash.c:  Throughout use underscored variants of 
the stat
         function family.

RTEMS doesn't have _stat, _fstat, _stat64, _fstat64 or _mkdir. We do have
the version without _.  Looking in sys/stat.h, it appears that these
are part of the libgloss support but we didn't notice needing them
until you made this change.

RTEMS provides its own mkdir() so we can ignore _mkdir().
But to use hash.c, we need to address the four stat calls.

I see two possibilities:

+ Define _stat -> stat, etc.  This would be a conditional
    in newlib's sys/stat.h.
+ Implement simple _XXX wrappers for RTEMS.

Which would be better in your opinion?
