Make finer-grained spectest targets

[tbrowder]

The Problem

Running a full spectest on a new branch will show no errors with a modified existing roast standard test, but trying to run the tests in its S* directory or as an individual test fails.

That is exasperating when trying to test during a core change because the existing spectest takes so long. A finer-grained spectest for use before a PR would be very usefule to me.

Alternatively, publishing the exact ./perl6 command for local testing of rakudo with single tests in t/spec/S* would be just as useful.

Expected Behavior

I would like to have a make target something like this:

make spectest-S26-documentation

Pretty sure you can already do something like:

make t/spec/S26-documentation/05-comment.t

[tbrowder]

@AlexDaniel, you are right, and it works as expected!

Where is that documented (pardon my faulty memory, but I think this is old ground and I just can't find it referenced)?

[AlexDaniel]

Don't think it's documented anywhere, but see here: https://github.com/rakudo/rakudo#building-and-installing-rakudo
Maybe add a sentence or two saying that if you want to run a single test, then you can do that.
