[U-Boot] [PATCH/RFC] env: always build env_embedded and envcrc

[Wolfgang Denk]

Dear Mike Frysinger,

In message <1248683475-2658-1-git-send-email-vapier at gentoo.org> you wrote:

But always building some tool that is normally not needed just adds to
the compile time.

Again, I see added build time as a con for this patch - but I'm
failing to see any pro?

If you have "external utils" that might need this, please add a
separate Makefile target so you can build this separately, but save
all the rest of us the compile time overhead.

Thanks.

Best regards,

Wolfgang Denk
