[config-patches] New O/S needing config support: NetBSD-8-derived OS108

[Nelson H. F. Beebe]

The latest config.{guess,sub} files that I pulled down yesterday
(internally dated 2019-05-2[38]) fail to recognize OS108, a
recently-released O/S derived from NetBSD-8.

My temporary workaround is to use

        ./configure --build=x86_64-unknown-netbsd8.0

Here are some things that could be used to identify this system:

* added package executables go into the /usr/pkg tree, like on NetBSD

$ uname -m
amd64

$ uname -p
x86_64

$ uname -r
8.0_STABLE

$ uname -s
OS108

$ cat /etc/release
NetBSD 8.0_STABLE/amd64
