sdk: load(sdk)

load(toolchain)
fix QMAKE_DEFAULT_*DIRS resolution with apple SDK, take 2 the code got factored out to an own toolchain.prf file, which is load()ed from default_pre.prf, so no change at first. however, on mac, we shadow toolchain.prf, and make it load() sdk.prf first. a side effect, it has become harder to disable the use of an sdk altogether: putting CONFIG-=sdk into a project file or the qmake command line has no effect now. instead, it's possible to put it into .qmake.{conf,cache}. to make it simpler again, it's conceivable to finally add qmake -pre, which would allow setting variables before default_pre.prf is executed. take 2: there was nothing wrong with the original patch, but in 5.8, CONFIG+=simulator_and_device moved from qconfig.pri to various prf files that would do it according to the simulator_and_device configure feature, which would be way too late for the "pulled ahead" sdk.prf loading. as simulator_and_device is now gone entirely, it is safe to re-apply this patch (mostly) as-is.
