commit 9ec4dadfbbcf94d284b7e489694f1fa9fd6647c0
Author: H.Merijn Brand <h.m.brand@xs4all.nl>
Date:   Sat Mar 31 16:31:29 2012 +0200

    Add ld_can_script probe to Configure
    
    With this new probe, requested by rafl, we could start building perl as
    it would be built on OSs like AIX and Windows and actually test visibility
    of the API and thus early detect if tests would fail on these restrictive
    OSs
