glsl2/Makefile: Add a 'make builtins' target.

This copies over a dummy builtin_functions.cpp and rebuilds a
bootstrapped version of the compiler, then uses that to generate the
proper list of builtins.  Finally, it rebuilds the compiler with the new
list.

Unfortunately, it's no longer automatic, but at least it works.
