Gnulib module: lstat

Portability problems fixed by Gnulib:
@itemize
@item
On platforms where @code{off_t} is a 32-bit type, @code{lstat} may not
correctly report the size of files or block devices larger than 2 GB.
(Cf. @code{AC_SYS_LARGEFILE}.)
@item
On Linux/x86 and Linux/x86_64, applications compiled in 32-bit mode cannot
access files that happen to have a 64-bit inode number.  This can occur with
file systems such as XFS (typically on large disks) and NFS.
(Cf. @code{AC_SYS_LARGEFILE}.)
@item
For symlinks, when the argument ends in a slash, some platforms don't
dereference the argument:
Solaris 9.
@item
On some platforms, @code{lstat("file/",buf)} succeeds instead of
failing with @code{ENOTDIR}.
Solaris 9.
@item
On Solaris 11.4, when this function yields a timestamp with a
nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range
@minus{}1000000000..@minus{}1, representing a negative nanoseconds
offset from @code{tv_sec}.
@item
On Windows platforms (excluding Cygwin), symlinks are not supported, so
@code{lstat} does not exist.
