The motivation to do that:
1. Now, llvm would use the stock config.sub. Before that we had an
uncommitted FreeBSD-related patch. Now, it has been upstreamed and
comes back. It means that it would be easier to update these files in
the next time (less magic knowledge)
2. Fix a typo for pseudo-CPUs: 32e[lb] -> [lb]e32, 64e[lb]->[lb]64.
One of these CPUs is used for PNaCl and it was not really convenient
to have a CPU that starts with a digit.

from the GNU upstream: git://git.savannah.gnu.org/config.git
1. It eliminates a local LLVM patch for auroraux (because, the
mainline config.sub has already got support of auroraux)
2. It adds several new recognized target cpus and operating systems
(in particular, PNaCl)
