Fixed bug #945

The configure script was breaking the substitutions into multiple fragments, breaking them across the substitution for the build rules.  This of course totally hosed the process.

I switched to using a more modern usage of AC_OUTPUT and added a post-process step that appends the build rules to the Makefile.
