[parisc-linux] hack to use HPUX boot loader

Phillip looked over some boot messages after being booted with the
hpux boot loader and blessed them, so things appear to be working well.

How about a COMMAND LINE?

If anyone wants to investigate a bit and work on head.S, it looks like
when launched from the current hpux boot loader that the args
passed to the kernel are

	int argc, char *argv[], char *envp[],

with some slightly bizzare stuff in the "environment", of possible
interest:

	env[2] - load address *of the boot loader itself*
	env[3] - size *of the boot loader itself*

argc will always be a low number >= 1.  If you had told ISL:

	ISL> hpux /boot/vmlinux a b c

then argc would supposedly be 4 and argv[2], for example, would be "b".
I suspect the argv[] should be copied to somewhere safe.

Note that this is very different from the statment in head.S:

         *      %arg3(=%r23) holds HALF(!) of the size of the BSS-Segment
