You can't use the mainstream kernel sources to compile an m68k Linux. 
You will need to apply the m68k patches to the source before you can
compile a good m68k based kernel.  You could pull 2.2.18 from the the
Linux-Mac68k site on SourceForge.  The following are instructions on how
to get the 2.2.18 source:

CVS is now hosted at SourceForge, so the procedures for checking out
sources have changed. Use these commands to check out the sources: 

$ export
CVSROOT=:pserver:anonymous@cvs.mac.linux-m68k.org:/cvsroot/linux-mac68k
$ cvs login
  (The password is blank. Just hit enter.)
$ cvs co -r linux-2_2 linux-mac68k
$ cd linux-mac68k
                           
If you want the unstable 2.4 branch instead, omit the "-r linux-2_2" in
the third command. 

This source had been used by a few Amiga owners to compile kernels for
the Amiga with good results before the 2.2.18 merge.  I have not had any
reports of success or failure with the 2.2.18 source.
