Patch from Eric Norum <eric@…>:

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).
