Yes, unfortunately you have to squash each of the patches into one
patch. Applying a patch which breaks a build, then applying another one
immediately after which subsequently fixes the break is not an acceptable
way of working I'm afraid. What would happen if we were to fall into
the middle of the two patches when bisecting?
