coreutils: import prebuilt manpages from Gentoo

As can be seen here:

http://lists.gnu.org/archive/html/coreutils/2014-11/msg00001.html

other people have run into the headache of trying to cross compile
coreutils, with the "help2man" problem (assumes host can run the
target binaries with "--help" arg to collect data for manpage.)

And since "current wisdom is this is working as intended" we are
largely left with no choice but to use the same solution and
abandon trying to generate the man pages at build time.  So here
we import prebuilt manpages.
