Minimal example:

define def
  echo first line
  echo second line
endef

Q=@

all:
	$(Q)$(def)


Output:

first line
echo second line
second line


I would expect the prefix character @ to be applied to both recipe lines of
"def". This is the case when the @ is provided literally. Provided by
variable, though, it is only applied to the first line of the canned recipe.
