Cross compiling for m68k/netbsd (was: Re: -fPIC for m68k/netbsd)

There should be not so many people interested in this issue.

I made small test program, which contains three files. When
you extract it and try to make 'a.out.pic' on m68k/netbsd,
it should work with '/usr/bin/as', but not work with after
market GNU 'as' (including cross compilation environment).

The error messages are,
	/var/tmp/cc08014a.s: Assembler messages:
	/var/tmp/cc08014a.s:10: Error: operands mismatch -- statement `jbsr _sub2,a1' ignored

I've tested with binutils-2.6, 2.81, or 2.91 but the result
is same. BTW, '/usr/bin/as' on NetBSD 1.3.1 is 1.92.3 according
to the program itself.

It looks that we can only generate fully statically linked version
of Kaffe on cross environment :-< If my assumption is correct, we
can put this into 'config.frag' or libtools. I prefer the later.
