1 Fix erlang tests so that they are always done in the same order and

     2 therefore generate test results that we can successfully compare

     3 against a master test results file.

     5 GNU make v3.82 introduced a change that caused this failure:

     9   * WARNING: Future backward-incompatibility!

    10     Wildcards are not documented as returning sorted values, but up to and

    11     including this release the results have been sorted and some makefiles are

    12     apparently depending on that.  In the next release of GNU make, for

    13     performance reasons, we may remove that sorting.  If your makefiles

    14     require sorted results from wildcard expansions, use the $(sort ...)

    15     function to request it explicitly.

    17 This change will be passed upstream.
