I'd say that make itself is sloppy wrt whitespace, where sometimes
newlines are considered to be whitespace, othertimes not.
For example, as you reported, gmake's $(strip ...) function treats
newlines as whitespace. But the "word" family of functions do not.
define x
foo
bar
endef
all:
echo $(words $(x))
echo $(words $(strip $(x)))
Given a choice, I'd prefer the word functions treat newlines as
whitespace.
