Details:

This patch adds a "writefile" function. This is similar to the existing "info"
function, except that it writes to a file.

This is useful when you have a Make variable whose value is larger than the
OS-imposed limit on the maximum size of a command line, and you need to pass
this value to a target. While there are workarounds, they are either slow or
don't work in the general case. For example:

http://stackoverflow.com/questions/512567/create-a-file-from-a-large-makefile-variable

http://stackoverflow.com/questions/7247667/writing-contents-of-makefile-131000-chars-variable-to-a-file

The "writefile" function also avoids another problem with passing arbitrary
strings through as command-line arguments: it avoids the need to escape shell
control characters.

The patch is against 3.82. Please apply it. It's small, it's localized, and it
helps Make scale to large build environments.
