Compiled usr.sbin/config.

Removed symlinks and files `obj' and `tags'.
Directory sys/pmax renamed to sys/mips.
Created a set of makefile includes for pic32 cross-build: share/mk-pic32.

 Tilden

-Workspace for experiments trying to port 4.4bsd to pic32mz microcontroller
+Project Tilden is an experimental port of 4.4BSD Lite2 operating system
+to a microcontroller. Microchip PIC32MZ family of processors was
+selected as a target. It is equipped with MMU with paging support,
+and 512kbytes of on-chip RAM. These resources seem enough to build
+a compact embedded system based on 4.4BSD.
