[PATCH] fix the YACC rule to fix a building failure

Upstream-Statu: Pending

The original rule will create the header file twice, one is that the header
file as the object file is created, other time is when create the C source file.
since YACC always has "-d" parameter.

This lead to a race when compile amd_tok.o, the header file maybe rewritten.

  |          ^
