cygport: Don't strip packed perl binaries

[Ken Brown]

TeX Live includes biber.exe, which is packaged as a stand-alone binary 
using the PAR::Packer module.  I've just discovered that the version 
I've been shipping with texlive doesn't function as a stand-alone binary 
because it's been stripped by cygport.  Is there a way that cygport can 
recognize such binaries and not strip them?
