Time to update config.sub & config.guess?

[John Klos <john%ziaspace.com@localhost>]

On IBM Power 8 system running Ubuntu ppc64le, I run in to the following 
trying to compile any NetBSD toolchain. Can we update config.sub & 
config.guess for ppc64le?

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 
0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.
