TODO: remove some items

Those items have now been implemented:

- mingw32 target
we have it now, and even mingw64 too

- mingw32 host
it is certainly possible to canadian-build a toolchain to run
in a mingw host

- Cygwin host
it is possible to build a toolchain in Cygwin, and it is probably
possible to canadian-build it as well

Disable at least mcpu32, m68010 and m68020. These processors certainly

do not like unaligned accesses.
