Add the new cdldr CD bootstrap loader. This patch includes the following: - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device. 2000-01-27 21:21:01 +00:00			`# $FreeBSD$`

Thanks to David's patches, we can now simplify these makefiles further, and just use PROG directly (without FILES). Suggested by: bde 2004-04-28 21:31:21 +00:00			`PROG= cdboot`

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 2004-02-06 21:58:32 +00:00			`ORG= 0x7c00`

Use -Wl,-N instead of the undocumented -N option for GCC. GCC forwards the -N flag directly to ld. This flag is not documented and not supported by (for example) Clang. Just use -Wl,-N.
