[kaffe] Notes on current for m68k/netbsd

[Kiyo Inaba]

Hi all m68k lovers,

Dalibor just committed modifications needed for m68k/netbsd. 
I'd like to summarize some notes about this. These modifications make
m68k/netbsd ports works again in some sense, but still there are
several issues remained.
	1) Supported engines: only 'intrp' and 'jit'.
	   Please EXPLICITLY specify these engines when configure.
	2) KJC
	   Still it does not work, or I only tested with a few test case.
	   At least HelloWorldApp.class.save works.
	3) ENOTSUP issue
	   syscalls.c uses this macro but, m68k/netbsd does not have it
	   defined. For the time being modify it to EOPNOTSUPP.
	4) memory protection
	   M_PROT something is not defined, or at least gcc can not find
	   defs for them in my installation. Use older version of source.
Issues 3 and 4 are not only for m68k/netbsd, and we are investigating
ways to fix them.

To keep source code structure similar, I modified m68k/linux specific
sources, and please have a try with this port also.
