According to SuS2
http://www.opengroup.org/onlinepubs/007908799/xsh/abort.html

    "The abnormal termination processing includes at least the effect of
    fclose() on all open streams, and message catalogue descriptors, and the
    default actions defined for SIGABRT."

It doesn't mention atexit stuff, so I think uClibc's current behavior
is not correct.
