bug#27946: 26.0.50; Commit 1f9f514e7c2ba41b0954d0141f99652f6a53a107 breaks the build on Ubuntu 14.04

[Philipp Stephani <p.stephani2@gmail.com>]

It appears that commit 1f9f514e7c2ba41b0954d0141f99652f6a53a107 breaks
the build on Ubuntu 14.04:

sysdep.c: In function ‘renameat_noreplace’:
sysdep.c:2695:58: error: ‘RENAME_NOREPLACE’ undeclared (first use in this function)
   return syscall (SYS_renameat2, srcfd, src, dstfd, dst, RENAME_NOREPLACE);

Probably the #ifdef there should also include RENAME_NOREPLACE.
