[ns] ns-2 configure script doesn't find tclcl

[Joris van Rantwijk <jorisvr@nikhef.nl>]

Hello,

I'm using ns-2.1b8 with tclcl-1.0b11 and I'm having a small problem with
the ns-2 configure script. I suggest a small modification to make it
a bit more friendly.

In my case, TclCl is not installed as a system library, but in some
directory specially for ns (through the --prefix option to the tclcl
configure script). The ns configure script now has problems finding TclCl,
even when I point it to the right directory with the --with-tclcl= option.
It says:
 checking for tcl2c++... no
 configure: error: Installation of tclcl seems incomplete or can't be
 found automatically.
 Please correct the problem by telling configure where tclcl is
 using the argument --with-tclcl=/path/to/package
 (perhaps after installing it),
 ...
But tcl2c++ IS present in the bin/ directory within the with-tclcl path.

I discovered that the configure script searches for tcl2c++ only in the
with-tclcl directory itself, not in its bin/ subdirectory. A small change
to configure.in solves this:
