What running program needs to have this environment variable set in
its environment? Is it the shells that are created by Makefile rules
when make dist is run?

What programs pay attention to this variable?

This will create a Makefile variable, which is different to an
environmental variable. That is, a line like "COPYFILE_DISABLE=1" will
appear in the generated Makefile, and this will be substituted
elsewhere in the Makefile if the COPYFILE_DISABLE variable is referred
to. However there is nothing there to change environmental variables.
