look for mkspecs in the project root, not next to every project

Browse Source 
qmake would look for mkspecs/ in the directory containing the current
project file. this makes completely no sense with recursive projects:
a) nobody would make per-project specs and b) specs meant to be global
would not be found.

consequently, we look for a project root when starting qmake and use
only that directory.
if .qmake.cache is found/set, we assume that to be the project root.
otherwise, we search for mkspecs/ the same way we search for the cache -
just to up until we find one or hit the root. if we are shadow-building,
search the build dir as well.
