whether a file needs to be made or not. If it returns a non-empty string,
when stripped, it will force the file to be made. If it returns an empty
string GNU make decides the normal way. Note that .MUST_MAKE does NOT have
to be expanded if make already knows the file needs building. Also, note
that for multi target rules it may be invoked for each file.";
