Languages harness

There are 4 ways to run a language test:

Overall Harness

    make languages-test

or

    cd languages && make test

Selected languages

    cd languages && perl t/harness --languages=pynie,punie

Per Language Harness

For almost all languages you can do something like:

    cd languages/tcl && make test

Run a single test for more detailed output.

    cd languages/tcl && prove -v t/cmd_lsort.t

TODO

It should be possible to use non-Perl5 test files, like for languages/perl6 or languages/pheme.

We are assuming that we are running out of parrot/languages; we are being called by languages/Makefile with an explicit perl.
