Eelco Dolstra 45081f330d * Append the version to the "name" attribute to make the store paths
of Hydra builds more distinct (e.g. "patchelf-build-0.5pre1234"
  instead of just "patchelf-build").  If the version isn't known,
  append at least the revision.

* Propagate the release name of the source tarball to Nix builds.
  Useful to provide sensible package names in channels.

# This function builds and tests an Autoconf-style source tarball.

# making it available through a channel). If `doCoverageAnalysis' is
# true, it does an ordinary build from a source tarball, except that
# it turns on GCC's coverage analysis feature. It then runs `make
# check' and produces a coverage analysis report using `lcov'.
