After 1.9.1 news I decided to send it now, because of "Support for the Mingw ARM toolchain".
I first wanted to do more tests, but I think this change is safe enough.

There's one other change I think about. At the moment we don't check for mingw toolchains when crosscompiling:
  if test "$cross_compiling" = "no" -a "x$enable_tests" != xno -a "$LIBEXT" != "dll"
  then
      WINE_CHECK_MINGW_PROG(CROSSCC,false)
Is there a good point for the crosscompiling check or am I free to remove it?
(It was introduced in c3c587eb1d340319cecf345528200cf4d26cbfb4)
