YACC as bison -y. In this way, we ensure that bison is being used, but

Added Makefile.spec to the list of files to copy to the object directory.

Modified Makefile.config.in to determine paths for directories (like
LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this
works better for symbolic links).
