Description
commit 189e9c93d7e (QTemporaryFile: Add support for Linux's O_TMPFILE) added the following snippet to qtbase/src/corelib/io/qtemporaryfile.cpp:
auto materializeAt = [=](const QFileSystemEntry &dst) { return ::linkat(AT_FDCWD, src, AT_FDCWD, dst.nativeFilePath(), AT_SYMLINK_FOLLOW) == 0; };
This fails to compile for Android using clang from NDK v15c:

Because of the ongoing changes in NDK versions r14-r15-r16 regarding unified headers and clang versions I also tried r16-beta2, but there the result is the same.
