I think this is a gitorious problem, happened to me too!

I had the same problem, but it happened to me because of leftover
configuration from a previous unsuccessful build.
To fix i did the following commands on qtbase folder:
 $git reset --hard
 $git clean  -dxf
and tried the configure step again. It should work..

Check if your target arch and host arch is correct in
the qtbase/mkspecs/qconfig.pri file(after ./configure).
