What was the configure command with GNU binutils?  An assembler for
m68k-elf and a linker for m68k-elf are separate from the native
i686-apple-darwin9 ones...  Having the target binutils and the target
C library installed before starting to build GCC are the default
prerequisites...

The GCC build tries to check the target C library unless one uses
the '--with-newlib' in the GCC configure. Then only the newlib
headers (from 'newlib/libc/include' in the newlib sources) will
be needed to seen in '$prefix/$target/include' and
'$prefix/$target/sys-include' (the second a symlink to the first).
In your case the $prefix will be '/usr/local' when no '--prefix=$prefix'
was given...

The target 'as' and 'ld' should be here...

The target C library binaries could be here...

The target C library headers should be here...

Probaly this script points to the native i686 'as'...
