Work around bug in Solaris 10 /proc file system:
/proc/self/fd/NNN/.. isn't the parent directory of
the directory whose file descriptor is NNN.  This needs to
be worked around at run time, not compile time, since a
program might be built on Solaris 8, where things work, and
run on Solaris 10.
* openat-priv.h (BUILD_PROC_NAME): Remove.  All callers changed
to use the following interface instead:
(OPENAT_BUFFER_SIZE): New macro.
(openat_proc_name): New function.
* at-func.c (AT_FUNC_NAME): Adjust to above changes.
* openat.c (openat_permissive, openat_needs_fchdir, fdopendir):
Likewise.
* openat-proc.c: New file.
[ChangeLog]

* openat.m4 (gl_FUNC_OPENAT): Add AC_LIBOBJ(openat-proc).
