The expansion of every variable and function must result in a single
line. You cannot expand into multiple lines.
There are two exceptions to this rule: first, you can expand into
multiple lines within a command script, so something like this works:
define FOO
@echo hello
@echo world
endef
foo:
$(FOO)
And second, the argument to the special $(eval ...) function can contain
multiple lines.
No other expansion can result in multiple lines being produced.
