Log Message:
make: prevent newline injection in .for loops

When a value of a .for loop contained a literal newline, such as from
the expression ${.newline}, that newline was passed verbatim to the
"expanded current body" of the .for loop.  There it was interpreted as a
literal newline, which ended the current line and started a new one.
This resulted in several syntax errors.

In cases like these, print a more precise error message.
