1) Build avoidance fails on a clean workspace because directory
$MY_WORKSPACE/tmp doesn't exist when mktemp needs to
create a forth subdir under that path.
Add a 'mkdir -p $MY_WORKSPACE/tmp' to ensure it exists
prior to mktemp.
2) Failed to rebuild kmods after a kernel change and
building with build-avoidance enabled. The problem was
a missing dependency cache that would have listed
the kmods as having dependencies on the kernel.
Reusing kmods from a prior build in conjunction with
a rebuilt kernel results int load with unusable kmods
due to a key mismatch.
Add the dependancy-cache to the list of artifacts to
syncronize as part of build avoidance. A primed
dependency cache will allow build-pkgs to determine
that kmods must be rebuilt when the kernel has changed.
3) Make sure $MY_WORKSPACE/$BUILD_TYPE/repo
symlink exists after a build avoidance build.
If no packages require a rebuild, it was missing.
4) Fix an error message that was puzzling while debugging
the above issues.
