If there are cinderblocks on the inside, then the outside layer isn't structural. Depending on how old the building is, it might serve a purpose for insulation - either an 'air gap' or to sandwich proper insulation material between two layers. But the building will stand without the brick. This is actually the 'normal' way of building anything under, say, 4 stories in most of Western Europe.
