Running tinderboxes with different flags has shown (numerous times
now) to be a PITA.  *PLEASE* line it up with the current CFLAGS,
or rather do *not* set CFLAGS by its own, but let "make foo" set
them as defined by sys.mk version from the compiled sources.

And if you feel that -fno-strict-aliasing is evil, why not dike it
out from sys.mk?
