* elf:
- kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
per emulation and contains pointer to respective probe function
- interp is allocated via MALLOC() rather than on stack
- elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
part of appropriate execsw[] entry

Two main changes:
Create a linux_elf64_copyargs that uses the linux specific LinuxAuxInfo
structure. This is only used on the alpha. i386 and m68k use the
standard elf copyargs function.
Since linux's approach to binary compatibilty is to look as much
like osf1 as possible, add all the osf1 syscalls that we have
implemented to the linux syscall table. This includes get/setsysinfo,
ported from FreeBSD.
In order for linux compat to work you must have COMPAT_OSF1, COMPAT_43,
COMPAT_09, COMPAT_12 and COMPAT_13 on also.
