perf archive: Don't try to collect files without a build-id
To avoid these error: [root@doppio ~]# perf archive tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat: No such file or directory tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat: No such file or directory tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat: No such file or directory tar: .build-id/00/00000000000000000000000000000000000000: Cannot stat: No such file or directory tar: Exiting with failure status due to previous errors [root@doppio ~]# More work is needed to support archiving symtabs for binaries without a build-id, perhaps creating a perf.data UUID + adding build-ids for the binaries copied into the cache and then have this perf.data session UUID be a directory with symlinks to the by now calculated build-id of the files inside it. Or just do an extra pass and insert the calculated build-ids in the perf.data header.
