[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().
