As Nestor points out, the "$l" in "$line" is expanded by make as the
variable "l", which is not defined and so expands to nothing.
Whenever shell scripting in make command scripts you _MUST_ remember to
escape all "$"'s you want passed to the shell.
na> I had the same problem. Do the following:
na> find $(TMPDIR) -name '*~' | while read line; do rm "$$line"; done
Note that this is not portable shell script syntax. If you want to do
it portably you need:
find $(TMPDIR) -name '*~' | (while read line; do rm "$$line"; done)
