build: Compile with large inode number support where possible On filesystems with large inode numbers, such as overlayfs, attempting to stat() a file on a 32-bit system using legacy syscalls can fail with EOVERFLOW. If we opt-in to more modern "large file support" syscalls, then source code references to functions like stat() are transparently replaced with ABIs that support large file sizes and inode numbers, such as stat64(). This cannot safely be done globally by Linux distributions, because some libraries expose types like `off_t` or `struct stat` in their ABI, meaning that enabling large file support would be an incompatible change that would cause crashes. However, SDL appears to be careful to avoid these types in header files, so it should be OK to enable this. Signed-off-by: Simon McVittie <smcv@collabora.com>
