Paul,
As Nikolay said, probably the easiest route is is to adapt an existing library
for your target. I used newlib. The board dependant stuff is in
<newlib-src>/libgloss/m68k for m68k targets.
Check the examples.
If you want to use gdb for debugging, you also need gdb stub.
This might help you:

Best regards,

Hi Paul,
Are you looking for specific functionality, or just generic m68k
support? If it's just generic, libgcc has support for some low level stuff:
https://gcc.gnu.org/onlinedocs/gccint/Libgcc.html
Then there are the newlib and eglibc, all of them are free software.
Kind regards,
Nikolay
