"""Set up tasks and build directory for a configuration.
This function creates the specified directory for files
related to the build process (not files used in the build of
individual components), removing and recreating it as
necessary; logs go in the specified directory for logs. The
separate directory for sockets is expected to exist and to be
empty; that directory is separate because paths to Unix-domain
sockets have a small length limit, so a short path in /tmp is
appropriate rather than the longer paths used for the rest of
the build.
As well as other files, a GNUmakefile is created in the
specified directory for controlling the build, via 'make all'
unless a more selective build of particular tasks is required.
