    Building perfcounter tools raises the following warnings:
    
     builtin-record.c: In function ‘atexit_header’:
     builtin-record.c:464: erreur: ignoring return value of ‘pwrite’, declared with attribute warn_unused_result
     builtin-record.c: In function ‘__cmd_record’:
     builtin-record.c:503: erreur: ignoring return value of ‘read’, declared with attribute warn_unused_result
    
     builtin-report.c: In function ‘__cmd_report’:
     builtin-report.c:1403: erreur: ignoring return value of ‘read’, declared with attribute warn_unused_result
    
    This patch handles these IO return values.
