perf tools: Fix cross-endian analysis Trying to analyze a big endian data file on little endian system fails with the error: 0xa9b40 [0x70]: failed to process type: 9 The problem is that header parsing is not done correctly because the file attributes are not swapped. Make it so. With this patch able to analyze a sparc64 data file on x86_64.
