Sorry for this nasty bug. I just fixed it.

I made use of "order-only prerequisites". Without that nice feature,
things would have been quite complicated:

    http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/5a325871b88a

In addition, I added a "cache" for check-requirements, as this
takes up to 1.5 seconds on each run of Make which is quite
annoying. So the requirements are only checked on the first run
of Make, and are re-checked only when our main Makefile changed.
That way, newly added requirements will always trigger a new run
of check-requirements:

    http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/eef5ab0c2a3b

I also added a quick note to the docs:

    http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/babebbce8689

I'm using the following timestamp file, because I didn't
find a better place for it:

    usr/installed/check-requirements

Maybe we should rename "usr/installed" to "usr/timestamps" or
something similar? What do you think?


Greets,
