libc/newlib: build newlib in the proper step

Currently, newlib is built in the start_file step, which is wrong, but was
needed when the baremetal integration was... well, 'unfinished'.

Now that we build the baremetal compiler from the final cc step, and a
proper core gcc in pass-1 and pass-2, we can move the newlib build to the
step do_libc, where it belongs.

     1 The m68k mcpu processor does not like unaligned access

     2 

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

     4 do not like unaligned accesses.
