QLibraryInfo::location(TranslationsPath) does not honor qtlibinfix

If I configure Qt with...

-qtlibinfix _myinfix

..., I expect QLibraryInfo::location(TranslationsPath) to return something like "/resource/qt_myinfix/translations". But configure creates an entry in qconfig.cpp that looks like...

static const char qt_configure_translations_path_str [512 + 12] = "qt_trnspath=\\resource\\qt
translations";

...but it should instead be...

static const char qt_configure_translations_path_str [512 + 12] = "qt_trnspath=\\resource\\qt_myinfix
translations";

Therefore QLibraryInfo::location(TranslationsPath) returns a wrong path when configureing Qt with qtlibinfix
