Anecdotally, such failures are generally more visible on system which
have both a "slow" single-thread execution paired with very high parallelization.

ippl/Source/Makefile.in has

```
y.tab.c: ippl.y Makefile ../Makefile.common
        $(YACC) -d $<

lex.yy.c: ippl.l Makefile ../Makefile.common
        $(LEX) $<
```

and it probably should look like this

```
y.tab.h: ippl.y
	$(YACC) -d $<

y.tab.c: y.tab.h

lex.yy.c: ippl.l y.tab.h
	$(LEX) $<
```
