To prevent ${prefix} from being expanded in the resulting
Platform.make file.

The current behaviour is intentional; it allows e.g.
"make install prefix=..." to work as expected.

The fact that make variables can be overriden on the command line
is[1] a significant factor in how Makefiles are structured.

depends upon whether the Makefile's author "gets" make.
