Run C binaries to detect incompatible compiler/kernel pairings instead of sniffing versions. updates #21196 Change-Id: I0debb3cc4a4244df44b825157ffdc97b5c09338d Reviewed-on: https://go-review.googlesource.com/52910 Run-TryBot: Bryan Mills <bcmills@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
