Note how SHELL now points to /bin/sh (nonwithstanding that the interactive
shell is still /bin/csh), and the build finishes.

>How-To-Repeat:
    Try to build lang/gcc34 with $SHELL pointing to a non-bourne shell. Note
that merely invoking a different shell from the commmandline will leave $SHELL
unchanged.
>Fix:
    I'm not sure I'm cunning enough to provide a clean patch, but a workaround
would be changing SHELL to /bin/sh, regardless of the current interactive 
shell.
