You can't use constructs like this, because of the way make(1) performs variable
expansions (see `man make' for details). If you really need something like that,
then you can use:
_USE_FACILITY:= `${ECHO} ${USE_FACILITY} | ${TR} "[:lower:]" "[:upper:]"`
USE_FACILITY=${_USE_FACILITY}
(note ":=" instead of plain "=" in the first assignment).
