  No mention of a library there.  I'd expect you to want newlib to go with
m68k-coff.

  And sure enough the build failed while making libgcc.a, which is built
for the target and hence needs the target's header files.  Check the
references in the FAQ to newlib and building the core C compiler followed
by newlib followed by the rest of the compiler.
