* unix/Makefile.in: Use new BUILD_TCLSH variable
to detect when we need to build a dynamic executable
that does not contain a burned in shared library path.
The avoids a problem when a user is building a new
version of Tcl but already has an older version
installed in the same prefix.
Build the tcltest executable without a burned in
shared library path to avoid the same problem.
Update shell and gdb targets to use this new
BUILD_TCLSH variable.
* unix/README: Cleanup outdated README notes.
Inform people that they should run "make shell"
to launch Tcl from the build directory.
* unix/configure: Regen.
* unix/configure.in: Define BUILD_TCLSH.
