Change PL/Tcl build to use configured compiler and Makefile.shlib

system, not Tcl-provided one.

Make sure export file, if any, is cleaned.

Tcl configuration is now read directly in configure and recorded in
Makefile.global.  This eliminates some duplicate efforts and allows
for easier hand-editing of the results, if necessary.
