Patch from Eric Norum <eric@skatter.usask.ca>:

Browse Source 
I've included a version of make/custom/gen68360.cfg that works with
    this.  Note that I've removed the option of using `-m68020
    -msoft-float -mno-bitfield' as an alternative to using `-mcpu32'.
    The alternative won't work with the new system (since it predefines
    __mc68020__ and not __mcpu32__), and didn't really work before anyway
    (since the newlib that gets linked was built with `-m68020
    -msoft-float' and so could contain bitfield operators).
