First round of cleanups to sys/boot/ makefiles:
- do not use PROG for what's not a real C program, - use sys.mk transformation rules where possible, - only create the "machine" symlink on AMD64, - removed MAINTAINER lines in individual makefiles, - added the LIBSTAND defitinion to <bsd.libnames.mk>, - somewhat better contents in .depend files. Tested on: i386, amd64 Prodded by: bde
