[coreboot] romcc changes for mingw32 environment

I succeeded in building the entire SerialICE tool set (host and target)
on mingw32. Most changes are in the repository already, but there are
two issues in romcc without a clean fix so far, so I thought I'll post
the patch for discussion to have it out in public.
As they're romcc related, I also added the coreboot list.
1. romcc seems to access memory after free. There's an xfree() call
removed in that patch, which is a thinly disguised free() call. With
that one removed, free_basic_block(..) works happily, with it present, I
get a segfault. Win32 seems to invalidate free'd memory by writing a
pattern (0xfeeefeee) there, and that trips up the next pointer deref.
There's probably a "sane" fix to that.
2. romcc uses open/read/close to read included files. For some reason,
read always returns 0 bytes, so that's an endless loop. I kept the
open/stat/close part, and replaced the read with fread (and fopen/fclose
to support it).
This might be solved in a cleaner way.
