Change 28222 by peter at peter_overcee on 2003/04/05 03:36:32

	make the kernel link, by any means necessary.
	
	peter at overcee[3:34am]~/fbp4/hammer/sys/x86_64/compile/GENERIC-593> ls -l kernel
	-rwxr-xr-x  1 peter  peter  1866185 Apr  5 03:32 kernel*
	peter at overcee[3:34am]~/fbp4/hammer/sys/x86_64/compile/GENERIC-594> file kernel
	kernel: ELF 64-bit LSB executable, AMD x86-64, version 1 (FreeBSD), not stripped
	
	Obviously, do not try booting it. There are a boatload of known-wrong things.
	Not that anybody could, because the i386 loader doesn't understand elf64.
	But this seems like a good point to get some sleep.
