another version update...
tcl was added back in, as the included tk/itk/itcl tends to get
confused when used with the system tcl.
optimized still causes segfaults on amd64, so optimized is
disabled there... (problem report submitted to brlcad)
files/patch-configure was added to prevent jove from being
built if emacs is not found, configure.ac on the project has
been patched, so next release should remove that, hopefully.
I'll take it.
