ALL configure scripts generated by autoconf accept --prefix.
It sounds like what you want to do is turn ${prefix} (substituted at
autoconf time) into PREFIX (a C preprocessor macro at compilation time),
using Makefile as the place to do the expansion so as to cover nested
definitions (for example, ${exec_prefix)\} defaults to being defined in
terms of ${prefix}).
That is easy to do; in fact, the gnulib configmake module does just that.
