No.
This actually turns out to be a long-standing bug in GNU make--or
rather, GNU make is behaving as intended but it turns out that this
behavior is not POSIX-compliant. The next version of GNU make will
handle this properly.
In the meantime I'm afraid there's nothing you can do except use a
separate script, or else switch to another tool (or version of sed) that
allows you to generate newlines without needing an actual newline
character; in Perl for example you can use the two-character sequence \n
and it is printed as a newline.
