Subject: break build if it would produce broken binary
X-Git-Tag: v2015.04~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6a4c542d316b3401f0840ac5378743191bca851;p=platform%2Fkernel%2Fu-boot.git

break build if it would produce broken binary

Add an error in known-bad case so that we don't produce broken and
hard to debug binaries.
