It's not, if the obj dir is inside ./work then surely the script has set
MKOBJDIRPREFIX to reflect that, and that's where it would be doing the

Is it possible you had run the script previously as root, and this time
you were not root?  If so, the object files from the previous run are
owned by root, and you don't have permission to delete them.
