[PowerPC64LE] Set up powerpc.powerpc64le architecture
This is the initial set up for PowerPC64LE. The current plan is for this arch to remain experimental for FreeBSD 13. This started as a weekend learning project for me and kinda snowballed from there. (More to follow momentarily.) Reviewed by: imp (earlier version), emaste Sponsored by: Tag1 Consulting, Inc. Differential Revision: https://reviews.freebsd.org/D26399
