It'll be just another dozen mails 'til I really get it, I promise.

So, by default, buildername, buildnumber, branch, revision,  and
slavename are set properties, see

The only way to set more properties is to actually write custom
buildsteps that do it,

Now, for workdir in particular, that would be a property on the
buildstep, not the build. It sounds more logical to me to have an
initial buildstep that would set, say, ALF_LIBRARY_BASE, and use that
property to set the workdir for the step that actually creates alf,
and then use the same base variable to set your ALF_LIBRARY_PATH for
make check.

As the current workdir for a step could be anything on the run, I'd
rather not set that as a build property.
