  Log Message:
  -----------
  Add `unifdef' directory to the Automake-based build.

`unifdef' is now compiled and installed in C-Reduce's libexec directory,
alongside C-Reduce's other internal tools.

This commit does *not* include changes to the CMake-based build process.
Contributions from CMake users would be welcome.
