qmake will now look for .qmake.super, just like it looks for .qmake.cache,
and the cache() function has a mode to write this super cache.
this allows the creation of aggregator projects like, say, qt5.
a notable difference to the normal cache is that this file is *not* added
as a dependency of the Makefile. this means that modifications done by
later sub-projects will not cause a re-processing of earlier projects, and
consequently that one should be cautious regarding what information to
store there.
another notable difference is that this file is read *before* the spec,
so the spec can use the variables from the cache without resorting to
$$fromfile() & co.

this is the source dir equivalent of .qmake.cache and can be checked
into the repository. it can be used to make project-wide settings, or
just to signal the presence of an mkspecs/ directory.

this allows the creation of aggregator projects, like, say, qt5.
this is not expected to have a negative impact, as no project could
reasonably expect a nested .qmake.cache to *not* take effect - in fact,
if the project was processed stand-alone, it would already use it.

when qmake runs into the new option(host_build) command, it will restart
the project evaluation with a host spec.
the new default host spec is called default-host (gasp!). it is
overridden with the pre-exising -spec / -platform option, while the new
-xspec / -xplatform option overrides the pre-existing default spec.
specifying -spec but not -xspec will set the xspec, too, so the behavior
is backwards-compatible. same for the XQMAKESPEC override read from
.qmake.cache and the environment variable.
the cleaner solution would be adding -hostspec, to be symmetrical with
the override semantics, but that would deviate from configure in turn.

now that the spec+cache are evaluated in a completely clean context
anyway, there is no point in re-evaluating them for build passes.

don't inject the build pass specific variables into the project even
before evaluating the .spec file and the .qmake.cache. they are not
supposed to base configuration on that - feature files should do that
later.
the immediate advantage of this is that base_vars is never manipulated
upfront any more, which allows for cleaner setup paths. also, we can do
more caching of the spec+cache contents.

This function calculates the topological order of variables.
We will use it to determine which and in what order to link
module libraries.
The function is not tied to libraries/modules only, but requires
the variables to be ordered to have their dependencies in the
[prefix]<var>.depends subvariable.
Due to the recursive nature of the algorithm it was just much easier
to implement it directly in C++ rather than in a qmake-language
function.
