$NetBSD: patch-config-scripts_cups-directories.m4,v 1.2 2015/12/02 21:14:16 leot Exp $

The '$' while loops expand the variables as long as possible so that no
references to other variables occur. This is necessary because fontpath
may be "${exec_prefix}", which itself may be "${prefix}", and so on. I
don't know how many levels of indirection are possible, therefore the
loop.

I'm also sure that this is not the Right Way to fix it, but at least it
works.
