    Add error reporting (via errno) to getauxval().

    [BZ 15846] As discussed in the recent thread on my $EXEC_ORIGIN patch
    and in BZ 15846, getauxval() presently has no unambiguous way of
    reporting an error condition.  It currently returns zero on error, but
    this may also be a valid result for some auxv entries.  As there is no
    clear invalid result for all current and future auxv entries, this patch
    sets errno (following a suggestion in the BZ entry).

    This version of the patch also adds documentation and tests for the
    value-not-found conditions in getauxval().
