Hello,
I do not think this is a good tradeoff between increasing code size
(cfg.mk) vs possible performance improvement. - Do you expect somebody
is going to use a system for building find release tarballs that is
totally memory starved and wil be saved by an additional 48 MiB?
OTOH -7e is almost two times *slower* than the default. 5.74 seconds vs
3.77 on i5-6500.
