  This adds an assertion in prepare_for_building.  This was useful for
verifying whether some subsequent changes were valid.

[I failed to reply-all, so I am resending this]

The code paths in buildsym are not very obvious, so it's hard to
verify that this will always be true, but on the surface it makes sense.
Given that it survived your testing, it LGTM.
