Need to remove ASCII tags on copied compiled executables for z/OS ASCII

 Untag compiled executables (perl and the .so files) after they are
 copied with File::copy because File::copy is marking them as CCSID 819
 (ASCII). The longer term fix for this could be to provide a syscopy on
 z/OS which would perform a _cp_ which on z/OS copies the tag
 information as part of the copy.
