For the kernel, you need -Wa,-m68030 -Wa,-m68851
as generic kernels need code from all variants in assembler pieces of
code; we use the m68020/30 syntax and add the others as hex codes

sys/arch/amiga/conf/Makefile.amiga does all the magic, normally; check it 

If this doesn't work anymore, something is broken. You might want 
to run one of the partial compiles with -S and check the output.
(Especially the one from a2kbbc)

And please check your generated Makefile.
