FS-8776 #resolve Support GNU make parallel builds

* Explicitly define dependency tree for several modules
* Enable parallel builds for libtiff and libspandsp
* Verify module is enabled before attempting build.  Allows
  the virtual targets to be used for ordering without forcing
  a build dependency.
