Make the kconfig-style build work in mingw:

* use relative paths in ldscript.ld and crt0_includes.h
* avoid use of dd(1) in xcompile
* build libregex for kconfig, if necessary
* work around missing utsname on win32
* unlink targets before rename on win32
* implement (crude) mkstemp for win32
* avoid open/read/close, use fopen/fread/fclose instead
* don't free certain data structures in romcc on win32 to
  avoid crashes (likely use-after-free())
* handle "\CRLF" and win32 style absolute paths (X:/ or X:\)
  in romcc
* make lzma (part of cbfstool) build on XP
* implement ntohl/htonl on win32
* handle CRLF in awk script
* set larger stack for romcc on win32
