Revert create_symbolic_link and both depending changes

This reverts commits r203136, r203137, and r203138.

This code doesn't build on Windows.  Even on Vista+, Windows requires
elevated privileges to create a symlink.  Therefore we can't use
symlinks in the compiler.  We'll have to find another approach.
