I've actually installed a lot of GNU tools as I've found them superior
to the native ones.

Yes, I found the same. Really it just couldn't find the C library. I
have it installed in the tooldir (/usr/local/m68k-coff in my config).

I am using newlib-1.7 which I got from cygnus: ftp.cygnus.com:/pub/newlib

You might also look at the crossgcc FAQ at
        ftp.cygnus.com:/pub/embedded/crossgcc/FAQ

I use the m68k cross every day. I built the same toolset for our various
host machines running Solaris 2.4, Solaris 2.5, SunOS 4.1, HPUX 9.
Actually I only built newlib once and just copied it around.
My toolset comprises:
        Compiler: GCC 2.7.2
        Assembler: GAS 2.6
        Linker: GLD 2.6
        Utilities: Binutils 2.6  (ar, strip etc)
        Debugger: Gdb 4.15.1
These aren't the most up-to-date versions, but they work for me.

I did do cross debugging some time ago using a serial line connection to
the target. There were a couple of stub files in the gdb package that I
had to include in my target code, plus a couple of simple functions to
drive the serial port.
