uic crashes on Windows when outfile=stdout

QTextCode::codecForLocale() returns 0 when compiled in bootstrap library , thus it crashes in QTextStream::flush().

Note: qmake generates (uic -o <file> uifile and thus does not crash).

To reproduce:

uic src\widgets\dialogs\qfiledialog.ui

Program received signal SIGSEGV, Segmentation fault.
