determine QMAKE_DEFAULT_{INC,LIB}DIRS separately for host and target

Browse Source 
note that in principle this leaves room for a race condition, as the
first project to determine the host config is not going to be the
top-level one.
in qtbase and qtdeclarative, this is naturally serialized via the common
bootstrapped libraries (bootstrap resp. qmldevtools). activeqt, qt3d,
qtscxml, and qtwayland all build only one bootstrapped tool each.
qtwebengine makes a fake host build to create files for gyp/gn; the
convert_dict tool is declared a host tool, but isn't actually built when
x-building anyway, and even if, it's serialized on the former. qttools
needs explicit serialization, though. no other host builds exist within
qt as of now.
