[Bug-cpio] 2.11 fails to build on Darwin

[Ludovic Courtès]

Hello,

GNU cpio 2.11 fails to build on Darwin/x86_64:

(From <http://hydra.nixos.org/build/477396>.)

This reminds me that cpio is continuously built on Hydra, using a fresh
Gnulib and a fresh Paxutils checkout as input:

  http://hydra.nixos.org/jobset/gnu/cpio-master

(See <http://www.gnu.org/software/devel.html#Hydra> for details.)  If
you’d like to enable email notification or otherwise customize it,
please let me know.

Thanks,
Ludo’.
