There is simply no way whatsoever that make is invoking the second line
before the first finishes.  The code just doesn't work that way.

Is this directory an NFS partition?  Maybe there is an issue where the
new file isn't visible immediately.

Or, maybe the copyfile.sh script puts the copy command into the
background then the copyfile.sh script exits before the copy command is
complete.  Try adding -x after the $(SHELL) line and see what's going
on.

Otherwise, I don't have any idea, but it's not the case that make is
invoking the second line before the first one finishes.
