For PR514:
* language specification files are no longer configured with "configure"
* add substitutions for %bindir%, %libdir%, and various llvmgcc related
variables needed in the c and cpp spec files.
* Implement the stubstituions in the Compiler Driver.
* Move st.in to projects/Stacker/tools/stkrc where it belongs.
