If you are using GNU make 4.0 or better you can use the $(file ...)
function to write to a file (there is no limit, other than memory, to
the size of a variable in GNU make and so no limit to the amount of
content you can add to a file with the $(file ...) function), then
invoke a shell script on that file instead of using "echo ...".
