+Subject: [PATCH] mkspecs/common/posix: fix !largefile builds on uClibc
+
+uClibc doesn't even define O_LARGEFILE when not configured with large file
+support, so ensure this define is only used when Qt is built with
+-largefile, otherwise the build fails with:
+
+io/qtemporaryfile.cpp: In function 'bool createFileFromTemplate(
+       NativeFileHandle&, QFileSystemEntry::NativePath&, size_t, size_t,
+       QSystemError&)':
+io/qtemporaryfile.cpp:197:57: error: 'O_LARGEFILE' was not declared in
+       this scope
