post-link error leads to infinite build test loop

[jasongrout]

With conda-build 2.1.3, and this meta.yaml:

package:
  name: testpackage
  version: 1

source:
    path: ./

test:
    imports:
        math

and this post-link.sh:

exit 1

I get an infinite cycle when trying to do conda-build. Here is an excerpt

ERROR conda.core.link:_execute_actions(319): An error occurred while installing package 'local::testpackage-1-0'.
