I'm baffled at your confusion.  Section 3 gives you the right to
distribute it.  In the case of a Yacc source file, the .c output is
"object code".

Object code is what a compiler compiles to, when it operates on
"source code", where "source code" is the preferred form for
modifications.  The source code is the .y file, and in the case of
Yacc source, the .c and .o files are both object code.
