If the issue is the maximum length of the command line that you can
pass from Make to djecho, then the limit depends on the machine where
it runs: the 16KB transfer buffer is shared between the command line
and the environment we inherit to the child, so if your environment
is smaller, you will be able to pass a longer command.

Since the environment matters, if a different version of Bash passes a
few more variables to the child, you get a smaller limit on the
longest command line.

Btw, please note that it's not at all certain that Make invokes djecho
through Bash in this case.  You should check that carefully: I'm not
sure whether "$(MASK)" has enough magic in it to force Make to call
the shell.  If you want to be sure Bash is called, add redirection to
the command.
