bug#17694: coreutils build is broken on Maverics (MacOSX v10.9)

[Robin Mills]

Coreutils is not building on Mavericks.  He complains about the architecture 
while linking libver.a to chroot (and every utility).

Workaround:
$ cd ~/gnu/coreutils/coreutils-8.22
$ arch="-arch x86_64" 
$ ./configure CFLAGS="$arch" LDFLAGS="$arch" CXXFLAGS="$arch"
$ make        CFLAGS="$arch" LDFLAGS="$arch" CXXFLAGS="$arch"
… fails after compiling when linking chroot.  Complains about libver.a
$ cp src/version.a src/libver.a       # nice little tweak
$ make        CFLAGS="$arch" LDFLAGS="$arch" CXXFLAGS="$arch"
$ sudo make install

Fix:
I haven’t investigate the “proper” fix.  The work around is sufficient for my 
purposes.
