I thought of that, and it turns out it does get recompiled.
L2CR_CONFIG goes into opt_ppcparam.h, which make depend correctly marks
cpu_subr.o as depending on.

That particular symptom - "L2 cache present but not enabled" - has gone
away, and I speculate it was actually me misreading; see my more recent
message giving timing test results for more.
