+Subject: [PATCH] tc: fix parallel build file with lex/yacc
+
+Building iproute2 in parallel might hit the race failure:
+	emp_ematch.l:2:30: fatal error: emp_ematch.yacc.h:
+		No such file or directory
+	make[1]: *** [emp_ematch.lex.o] Error 1
+
+This is because we currently allow the yacc/lex files to generate and
+compile in parallel.  So add a simple dependency to make sure yacc has
+finished before we attempt to compile the lex output.
