One also needs to generate the 68k 'as' program, and place it in a path
something to the effect of:

/usr/local/lib/gcc/sun3-sunos4.1.1/2.0/as

Also generating the 'ld' from the binutils package would be useful for 
creating the final executable, and placing it in the same path  position.
However, at the last 'link' one needs the sun3 libc.a or equvalent, if
one wants to actually run the program on a sun3. There's the rub, one needs
a sun3 to borrow the libc.a from..

There is the 'glibc-1.02' libc equivalent, but it is in it's initial phase
of release and so may be somewhat difficult for those who are not use to
dealing with new software (but how else does one learn if not by doing).

At the point where the 'make' bombs on trying to make 'enquire' you will
have a cross development package, in terms of cc1 cc1plus, libgcc.a etc.
But some of the final steps will have to be done on a sun3.

I for the most part use the cross environment to generate stand alone
code to run in single board computers so I done have the need to
get all of the sun3 stuff up and fully generated. Usually I can
stop at the libgcc.a functions which implement the multi-precision
math stuff. (I avoid the float problem for the most part as well).
