Remove -arch argument and #define QT_ARCH from configures Do not try to detect the host or target architectures using uname or similar, and do not override with the -arch or -host-arch configure arguments. The configures will still accept the -arch and -host-arch arguments, but it ignores them and instead outputs a warning stating that these arguments are obsolete and should not be used. Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler target. This is done by running qmake (twice when cross-compiling) on config.tests/arch/arch.pro, which preprocesses a file that contains all knowns processors. On Windows, configure.exe has never run any config.tests before, and does not currently have a function to run a program and capture its output. Use _popen() to accomplish this (as qmake does for its system() function). This needs to be done after qmake is built, as does the mkspecs/qconfig.pri generation. As a side effect, the configure steps have been slightly re-ordered, but the overall result is the same. The displayConfig() call is moved to just before generating Makefiles, so that it can show the detected architecture(s).
