Check how gunzip can end up with #!/usr/bin/bash as the interpreter

Spotted by thor, unintentional bash being picked up.

Basically for certain packages (gunzip, liblzma seen as problems) - if there is a /bin/bash on the build host they'll use that as the invocation script instead of a standard IRIX shell like /bin/ksh.

Quick fix: Edit the /usr/didbs/VERSION/bin/gunzip script and change the shell to /bin/ksh.
