crosstool-ng 1.19.0 fails to build i686-unknown-mingw32

[Drew Bliss]

The x-tools directory appears to be cleaned up and recreated when running ct-ng build, so any manually created directory is gone by the time it gets to the point of needing it.

Back in Aug 2012 the same issue was reported with 1.16 and a user said that this patch reordering steps fixed the problem.  It doesn't appear to fix it with 1.19, plus the patch was considered undesirable since it breaks non-mingw builds.

mkdir -p .. of course!
