Upgrade to the latest version 1.4. It will be _required_ for TCL 8.3.2 and
above, and helps the earlier versions too. Remove the patches and provide
our own Makefile.bsd instead. Also, remove the WITH_TCL8? spaghetti and use a
simpler TCL_VER?=8.3 aproach. Note, that this port now assumes the usage of
TCL_STUBS.
