libc/mingw: do not remove support symlink

Under mingw, it seems that there is a mix between the traditional /usr
directory, and a similar-purposed /mingw directory (both in the sysroot).

Currently, we create /mingw as a symlink to /usr, and we removed it in
the libc-finish step.

Unfortunately, this prevents the pre-processor to find the headers.
Keeping the symlink makes it magically work...

     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.
