Part of the problem is that TCL_RPATH only gets used inside
CC_LINK_SHARED.  CC_LINK gets set to $(CC_LINK_SHARED) only if you're
building shared krb5 libs.  If you have a shared tcl lib and aren't
building shared krb5 libs, I can see how it would fail.

The easy solution to this would depend on whether it being possible to
have multiple -R or other equivalent RPATH flags concatentate on one
compiler command line.  More difficult solutions exist, but they
involve things like making a special CC_LINK_TCL_PROG variable or
something like that.
