patch for SGE: using tty over qrsh

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hi

with pkgsrc/parallel/sge's qrsh, it seems impossible to launch a job 
that uses a terminal. The attached patch seems to fix that problem at mine.

Any comment? Should it be committed in pkgsrc? Should it be propagated
upstream?
